Storage issue (Phantom partition?) - Sprint HTC One (M7)

So my One has been well above 20gigs of used space for some time, With an average of about 3 gigs of free space at any given time. I've checked my sdcard folder and it is about 5gb of space total (with downloads and everything else). There have been occasions where I plug the phone into USB and go to a folder quick and the files are ones I've never seen before (example in downloads folder the files are different then my actual downloads folder). I also have a directory 0, emulated, and legacy inside of Storage. These are exact synced copies of sdcard. Each taking up the same space (so 4x the actual amount of used space) and if I delete a file/folder for anyone of these directories it removes it from all including the sdcard.
Has anyone experienced this? is there a way to fix this without wiping the entire phone clean?

Do you go between AOSP/Sense roms? I don't see it anymore but it used to happen back when AOSP first starting coming out for the phone. It had to do with the multiuser support. It would leave all your Sense files but it would move the AOSP folder so you couldn't access them. Flashing a sense rom would let you access those files. I believe you can also access them by using a root explorer (es file also has a root option) and going up to /data/media you should be able to see those files and /data/media/0 should be the AOSP files.

sdcard "01" folder in internal storage

Today, I have experienced a very "odd" problem. I have just found out that there is a folder called "storage" visible in my Internal Storage.
When I thought that, since it was visible, it did not contain much useful files (Only 2 xml files I found which would be in both internal and external storage) so I deleted that folder and everything in my SD Card and Internal Storage vanished.
I found out that the "storage" folder had a link to both storage devices but the weird thing is, why was that there and why is it visible? I could of sworn that I have never seen that before on my Xperia Z...
Can anyone else see their "storage" folder in the internal storage or is it just me?

but this is totally different from what I have experienced.
From Windows, Internal Storage would have a folder called "storage" with another folder called "01" inside the storage folder. So "Internal Storage/storage/01/" if it was read on a Windows PC. inside the storage folder, there is just 1 folder called "01", nothing else. inside "01" folder, there are ONLY 2 .xml files which are the same as the 2 .xml files you would have by default in the root of your Internal and External Storage.
In short- Internel Storage has a folder called storage, inside storage has a folder called 01, inside 01 there are only 2 .xml files. The strange thing is, if it were linked to Internal/External Storage, why only 2 .xml files are visible in the 01 folder?
EDIT: When I tried to delete the storage folder (At the time I did not know that it was linked) Windows loading bar for deleting files did not move so I had to cancel it. Once cancelled, everything in my external/internal storage was wiped off. Thankfully, I recovered most of my lost pictures with Recuva
Not sure but I think this folder came somehow from the recovery maybe a bug.
I hope you didn't lost important things.

Yes, this is very strange. I remember when i did see this after i bought my phone i was thinking this must be an bug. Another thing, in root i also have a folder named: ext_card and it is the same as sdcard1 here. Sdcard1 is my microSD card i have, but why so many folder linked to the same folders.
At root i go to storage, inside i have folders: emulated, removable, sdcard0, sdcard1 usbdisk.
Inside emulated i have 0 and legacy. etc etc
All of them are linked and goes to the same internal card and external card,

If it really is a bug, we need to know what did actually cause this to happen.
And yeah, Recuva was really useful for me

Too many linked folders make it confusing, why would there be a linked folder visible in the Internal Storage though? this is what is really confusing me right now.
Need more reports if any one else has found this mysterious "storage" folder in their Internal Storage...
im not sure but if everyone with this folder are running 4.2.2 it is for the multiuser or multitasking feature of jellybean 4.2.2

Strange, this is the first time I have ever seen this. I only saw this folder today and I have been on custom roms based on stock xperia firmware android 4.2.2 for ages now... Why would it appear just today? I don't think multitasking will cause this to happen since it doesn't create any folders/files related to it (afaik).
I've had something like this happen where in emulated/0 (my main internal SD storage) there was another 0 folder that freaked out recoveries and such. I had the similar "can't delete from windows" thing, but using a in-recovery file manager I just deleted it, problem solved. tl;dr if you want to delete it and its causing problems delete it from recovery.

exactly what im talking about. lots of threads in the htc one forum about it and being this device was released with 4.1.2(like the htc one) and has recently been updated to 4.2.2(like the htc one) maybe its the same thing, not saying it is because i dont know. just sounds like the same thing

Windows did not make any progress in deleting it, it was stuck on the Preparing to delete... window. Once I cancelled it because it took too long, everything from sd card/ internal storage was gone. All because of that storage folder inside my Internal Storage...
I know about the emulated/0 issue (From previous HTC One X Android 4.2.2 AOSP roms) but this seems to be completely different from it.

I don't think it has anything to do with an upgraded android version. Like I said before, I have been on Android 4.2.2 a long time now (Upgraded when the firmware first came out) and I have never seen this folder before. I have just seen it yesterday. Another strange thing is that after I attempted to delete the storage folder, Everything was gone INCLUDING that storage folder. I haven't seen the storage folder after that happened. I'm going to go flash another rom and full wipe to see if the storage folder pops up again.
EDIT: Right, no there is no more storage folder in Internal Storage after a full wipe and formatted everything! Very strange indeed...
Wierd storage folder symlink inside internal storage!

I know this is a very old thread but I face the same issue in Android 5.1.1 now and I too deleted the folder named storage only to see that all the data from the sd card has vanished because of that. Any idea what caused this buggy symlink to be created?
All my data is now gone because I just deleted one folder inside my sdcard, and I didn't even think to backup anything since I didn't even dream that deleting a single folder will delete the parent folder! Again recuva was my friend but still I am not able to recover everything in internal storage, any suggestions on what to use to scan the internal storage?

Did you upgrade to newer firmware using a zip? That's a common bug when upgrading via zip.
The only proper way is to backup ur entire internal storage and flash a full ftf. Then you will not have the annoying symlink.

I did do a factory reset before flashing a new firmware. Not sure what else I should do..
And as for the internal storage recovery, I followed these different guides but raw file using vhdtool and recuva did not give me any single file that was last present in my internal memory and even extundelete didn't return any single file that was in the internal storage, some of these tools return hundreds of text files and images that I had no idea was in my internal storage but none of them return me any of the hundreds of images and videos that I was sure were in my internal storage.

Yes but if you factory reset on 4.4.2 (for example) and then flash 5.0.2 fw via zip in recovery, you will get the annoying folder symlink.
The only way to upgrade to lollipop is by flashing a full ftf (which will wipe internal sd) after that you won't have the annoying symlink.
But you flashed zip instead of ftf and discovered the folder symlink which seemed not harmful to delete so you deleted it. Right?
Then there's no chance in getting the data (photos etc) back.
I was the same situation as you, twice, I tried every possibility to recover my photos but it ended up with nothing. Everything was gone.
On a mechanical harddrive, when you wiped data, the data will only be gone when the wiped sectors are overwritten (e.g. format harddrive, which overwrite with empty buffer).
As long as the wiped data in those sectors are not overwritten, you'll be able to recover almost all - if not all - data you deleted.
On flash memory instead, (such as ssd drives and internal storage of our phone) deleted data is immediately deleted.
(that's also one of the reasons on Android, you never have to defragment the internal sd, same story for an ssd)
I'm sorry for u to say but I'm afraid you're unfortunately lost the photos and there's no way to get it back.
But my advice to you is:
Never upgrade between android versions (e.g. 4.4 > 5.0) using a zip installable.
Only use full factory images (ftf), they will wipe internal sd in order to get correct mappings so backup everything before flashing.
Once u on a firmware, an update to the same firmware is allowed (e.g. from one 5.0.2 rom to another 5.0.2 rom).
I hope it helps u in the future.

Thank you very much for the detailed explanation, after wasting two whole days trying everything described anywhere in the internet for recovering data from internal storage, I have also learnt it the hard way that it won't be possible to recover my data. Anyways the good news is google photos had backed up most of my photos, so it would actually be the call recordings, whatsapp history and other documents that I would have to loose permanently.

As for the upgrade issue, is this only for lollipop or any android version? I have never seen anything similar when I upgraded from 4.0 to 4.1 or 4.2 to 4.4 e.t.c. If I shouldn't use zip installable to upgrade android versions how else do I upgrade to kitkat or lollipop? I don't think there are any factory images published for lollipop for my phone since support for it ended long time ago.

Am again reviving this old thread as today I deleted a folder named sdcard inside my oneplus 3's internal storage and lost everyrhing. Though I had never upgraded my phone using any zip file and always went with the OTA update
I also made a thread https://forum.xda-developers.com/oneplus-3/help/strange-t3537998

[Q] Lost most of my internal storage?

Today when trying to free up some space on my HTC One (S-OFF, rooted, latest FW, etc), with the phone connected to the computer I cut and pasted the 'storage' folder into a folder on my computer. After this, most of my internal storage folders were gone, most notably all my Camera pictures. I looked in the folder that was copied to the computer and these folders aren't present. I also tried to do an adb pull from the root directory and the missing files weren't there either.
Looking at my phone storage, it says i have 20GB used by 'Other', which gives me hope that these files are still somewhere on the device. I did a search in a few applications looking for jpg files or any lost files but didn't come up with anything.
Has anyone else encountered this or have any idea if these files are still somewhere on the device? I know it was a stupid thing to do and didn't have a cloud backup set
Could you see the photos before you cut and pasted? What you've described doesn't sound like it should have caused your photos to disappear, but an upgrade would.
On a 4.1 ROM, the sdcard points to /data/media. On a 4.2 and beyond ROM, the sdcard points to /data/media/0. I would have a look in /data/media.

Mysterious files...?

Hi everyone,
Just rerooted my phone and installed Viper rom 6.2! I love it except the fact that there are some mysterious files on my phone, and 7.53 gigs worth! I am pretty sure that these are old installs of many different ARHD versions, but how do I delete them? I tried the super wipe script, but they still are there. It shows up under the "other" category in the storage menu in settings if that helps.
Thanks!
Closer...?
I just found some folders under storage that all contain the same files, /emuated/0 and /emulated/legacy/ so I did some researching. I realize that these are all linked to one another, but it still adds up to ~7 GB. The only way that it would get accounted for in the storage menu is under the "other" section right? I have tried to use root explorers to find the "other" files, but I cant find them. Is the /emulated folder taking up all this space?

/emulated/0 and /emulated/legacy are 2 different mounting point linked to the same partition. They are not duplicated files, if you delete it, you will loose everything in both folders.
Maybe you have some nandroid backup taking space from your storage?
Hmmm... Just checked in TWRP for any backups but it said there weren't any, so could the two folders legacy and 0 be actually taking up data because they contain duplicated files?

Strange storage free space issues

I'm very confused about the storage on my Moto G 2nd Gen 2014, running stock KitKat.
If I look at System Settings - Storage, for the Internal Storage it shows Total 5.51GB, Available 1.08GB, Apps 6.06GB (what!), Pictures 7.09MB, Audio 220KB, Downloads 24.49MB, Cached data 389MB, Misc 316MB.
Link2SD - Storage Info shows the same 5.51GB Total, 1.08GB Available for Internal /data and SD Card /storage/emulated/legacy.
When I look with ES File Explorer, it shows 5.51GB Total and 4.43GB Used for my internal SD (/storage/sdcard0 or storage/emulated/0). However, checking the properties of the folders, they don't add up to anything like that and if I run SD Card Analyst with Root Explorer and Show Hidden Files enabled and tap Directory Analyse it finds a total of 735.78MB, with Apps being only 42.30MB, Others 460.79MB, Audio 194.90MB, Picture 15.19MB, Document 17.79MB and Video 4.82MB. In the folder view sorted by size it shows Android 402.12MB, Recordings 109.34MB, voix 82.82MB, TunnyBrowser 50.58MB, com.alk.copilot.mapviewer 27.20MB, Download 24.41MB, six more folders under 10MB and 40 more under 1MB, with about half of those showing 0.00B.
So can anyone explain what's going on here, as I'm completely baffled?
Just bumping in the hope someone will see this who can help me.
Depending on how an app works when it stores it's data on the microSD it can still show in the Settings>Storage as on the internal memory (WoT Blitz did this when I had that installed) so that can make your apps look like you have 6.6GB on the internal memory, also in a file explorer the directory in which Android, DCIM, Music, Ringtones ect. is not the 'top most' directory, in ES File Explorer you can hit the '/' (also called Device) in the top bar and there are a load more files there. If you do a 'Select all'>Properties does that come close to the 4.4GB space used?

Hmm, I am using Obb2SD to move all my game data from Android/Obb to the external SD card, so maybe that's confusing it but that seems like it could be a problem as if it think the internal storage is full even when there's really plenty of space free, I imagine it will start throwing up errors and won't allow me to store anything else on it, which rather defeats the point of moving the games in the first place.
If I do select all->properties from / that includes my external SD as well and totals 46.42GB. Even if I unselect /mnt and /storage it still comes to 8.03GB which can't be just the internal storage as that's only 8GB in total and I supposedly have 1.43GB free on that. Just /data is 6.21GB.
You do know that your internal storage is a combination of your phone storage and internal storage right?
In case you didn't know just open root explorer and go to data folder (long press and select properties) and calculate how much storage it use...then do the same things with systems folder...then combined data storage + system storage + internal storage used and you will get almost the same amount like in settings/storages show you...
Sent Using My Xiaomi Redmi Note 4G
When I say Internal storage I simply mean that which is not the external SD card. I don't know what the difference between phone storage and internal storage is though, as far as I'm aware there's just 8GB internal storage.
Checking the properties for /data shows it as 6.21GB (6.31GB Used), so I suppose with 1.08GB available that totals 7.39GB which could be close enough to 8GB to be correct. /system is 1.17GB. Still doesn't make any sense that Settings - Storage and Link2SD shows Total 5.51GB, 1.01GB Available but Apps as 6.06GB. Nor does it make any sense that the Homepage in ES File Explorer shows 4.28GB used on 0 but tapping that, which takes me to emulated/0 and selecting everything, Properties only shows 700MB used.
Doing directory analyse on /data shows the majority in Others 3.70GB, then Apps 1.95GB. It's a pain there's no way to see how much storage is used by each folder without checking Properties for each one individually but if I untick all the folders starting with a then the total is 4.06GB (4.15GB used), so there's about 2.15GB in those folders. Unticking all the folders starting with b through d drops it down to 2.07GB (2.12GB Used) so they account for another 2GB. Digging deeper I can see that /data/app uses 1.73GB, /data/app-lib uses 432.15MB, /data/data uses 1.25GB, data/dalvik-cache uses 717.77MB, /data/media/ uses 554.41MB, /data/sdext2 uses 272.20MB, /data/user uses 1.25GB and everything else is inconsequential. Adding those up comes to roughly 6.2GB, which exceeds the Total 5.51GB that Settings - Storage shows, even without adding the 1.17GB from /system.
None of this helps me understand what in those folders is using up all the space though, so does anyone know of an app that will show the space used by folder, like Treesize for Windows?
Can no-one help me make sense of this? The weirdest thing is that 0 (Internal storage) in ES File Explorer's Home screen shows 4.28GB but opening that folder and selecting all the folders gives a total of only 700MB, which doesn't make any sense.
I see that Titanium Backup can produce a list of apps sorted by space used, so I'll try adding those up manually and see what they total. I have linked a few large apps to the external SD with Link2SD though, so they shouldn't be using any internal storage and I'll have to subtract their amounts from the total.
Well I decided to wipe data and dalvik-cache (i.e. factory reset) from TWRP and start again, to try and get to the bottom of this.
TWRP showed about 370MB out of 5.51GB used after wiping. After booting, this was about 560MB (I guess due to the dalvik cache repopulating, currently 258.98MB) and by the time Google Play had finished updating the pre-installed apps, this had risen to 1.27GB.
The majority of this, 1.17GB, is in /Data. Settings - Storage shows 4.24GB out of 5.51GB available. ES File Explorer is a bit stupid, as it shows the same in the Homepage the same for 0 (i.e. 1.27GB used out of 5.51GB) but tapping that links to emulated/0 (which is just an alternative path to /storage/sdcard0), which only has a total of 4.32MB in it. What the Homepage shows is actually the used space from root (i.e. /) so it should show and link to that, not /storage/ emulated/0.
Another anomaly is that /data/data and /data/user are alternative paths to the same place, containing 230.99MB, which results in it getting counted twice, so really there's only a total of 965.51MB of files in /data, not 1.17GB. Obviously as /data/data grows, that's going to result in even more space being doubly allocated and thus unavailable, i.e. if I have 1GB in /data/data, it's going to reduce my free space by 2GB.
I also notice that /data/app contains all the apks for the apps that are installed. I thought apks were just install packages, like Windows msi or exe installs and that when installed they unpacked to somewhere, so isn't it just wasting space keeping all of the apks here? It's only 357.19MB at the moment but when I checked it before I factory reset it was 1+, maybe 2+ GB, so that's obviously a lot of space to waste out of 5.51GB.
Hopefully someone can help me clear up these questions, as I don't want to start reinstalling all my apps yet if I might need to wipe it all again to reset it. I've backed up everything with Titanium but it's still quite a hassle, as there doesn't seem to be a way to make a list of installed (as opposed to backed up but not installed, or frozen) apps before wiping and then restore just those afterwards, so I'll have to go through the list and try and remember what I didn't have installed before and de-select those.

"thumbdata3" and Available Space

Hi,
A few days ago I found out that there were two files called thumbdata3 in "DCIM/.thumbnails" that were occupying around 6 GB between the two. I deleted them, and did the workaround of creating folders with the name of the files. After doing that, the files haven't been created again, but the available space hasn't increased. Before deleting the files I had 750 Mb, and after deleting them I still have the same amount of space.
What should I do to recover the amount of space occupied by those files?
I have a Xperia Z3+ with a stock ROM (5.0.2), unrooted.
Did you delete the files with a filemanager that has a "Recycle Bin" and the files are still there ?
That's a really weird bug, but seemingly not so seldom that no one ever has seen it before

I deleted the files with a file manager called "Solid Explorer" which doesn't include a "Recycle Bin." Moreover I don't have a SD Card, therefore I'm sure that the files were deleted from the internal storage.
