[Q] CacheManager - One (M7) Q&A, Help & Troubleshooting

I was just looking through the Internal Storage of my HTC One and in the .data folder is a folder called "CacheManager" with almost 2000 files inside that are about 15-50kb each. There are multiple files created each day and go back all the way to when I got my phone. Can anyone tell me what these files are and if they are safe to delete?
Thanks

Can anyone tell me what CacheManager is or if you also have this on your device too?
Thanks

Its exactly what the name says ... "Cache Manager" ... its a quick save for all kind of small image files which can be used locally instead of fetching from the web or other places ... i believe you can delete the whole thing ... it will just start caching again

Thanks for the response. I figured that each app has its own cache and the browser has its own cache, so what's being cached in CacheManager? I couldn't find any information about it on the forums or anywhere online.

I was clearing some of the caches on my apps but noticed that my CacheManager folder is still growing. Almost at 3000 files now. If it's not app's cache, then what is it? I'm just curious because I've never had this folder on all my previous android phones.

Has anyone learned more about what this CacheManager folder contains?

I too noticed this folder cache manager under .data growing despite clearing my cache via app functions. I deleted the whole folder since I couldnt delete the individual files. Everything works still and the folder thus far hasn't recreated. Edit ... The folder did recreate later... But the 8000 files within did not.

[Q] Double Image in Gallery

Hi there..
I update my SGS to Froyo last 2 days.. and yesterday I apply Voodoo 5 on it.
But today I just noticed that any images from my external SD will appear double in gallery.. dunno when it started to happen.. is there any way to fix this?
thanks
Im my case was 5 for each original, and with a lot of problems to delete the "non-real" ones...
thats hurt.. anyone can help here?
Yup! Just go to Application Manager, then easily clear cache for Media Storage! Ta-Da! No more duplicate images!
(It made my ringtones reset, but I could live with it!)

If you have Root Explorer
GO into /dbdata/databases/com.android.providers.media
and delete both the internal and external files
Reboot

Great hint, just wondering though if there is any way to have an app or script run at boot-up to do this for you, so people don't have to do it manually every time their gallery has a fit?

[Q] un-deletable 0kb files HELP !

Greetings from sunny ??? nottingham
I have a folder with a bunch of files that all show as 0kb that i can not remove.
Does anybody have an idea how i can get rid of these?
The story so far....
I am/was on rocket rom v2, previously i had put the google currents app on, but that was a couple of roms ago and i have not put it back.
I started having a few odd problems and realized my int sd was full. i eventually narrowed it down to a google currents folder. this was not so easy as any app that tried to scan the int sd in any way would crash or freeze. Even in manage apps it would only show details of apps from a to c any after that hung on 'computing'. i managed to delete over 5 gb from that folder, all except one folder.
Now i am left with a folder on the int sd inside the android/data folder called 'com.google.android.apps.currents' inside that is a folder 'cache' inside that a folder 'blobs.120.1184434912' inside that a folder thats a bunch of letters and numbers, inside that a folder 'att' and finally inside that a bunch of files all with single letters, numbers or symbols as there filename and all 0kb in size.
These remaining files and folders i can not get rid of.
I have tried....
Delete with root explorer and a couple of other file apps crash's or locks
Cut and paste elsewhere fail
Connect to computer and...
Delete fail
Move fail
Erase fail
Unlock freezes pc
Change permissions blocked
Re-name fail
Scanned with virus and spyware progs clean
Delete with dos fail
Factory reset fail
Factory reset with format usb crash's or locks
Flash a pit file in pc odin Still there
I wouldnt mind just leaving them there, but as i say any app that in any way scans the int sd crash's or freezes this makes the note almost un-useable.
I'm sure I've missed a few things i have tried but you get the point.
I have searched xda and the web as best i can and tried pretty much every idea I've come across.
Help !!!
Please !
What an odd problem....
have you tried aroma file manager?
Thanx p107r0
I havent tried that particular file manager, many others though.
Downloading it now, very busy next couple of days so will give it a go as soon as i can.

Cant you try copying all your important information off the sd then formatting it?

Unfortunatly i have formatted it several times now and those files still remain.
Are you familiar with adb tools? You could try using adb to delete the files.

Hi Postmonkeh
Unfortunatly abd is over my head, i wouldnt have a clue what i was doing.
Maybe i need to do some learning Do you know if theres a basic tutorial anywhere ?

It's fairly simple once you get the hang of it, but i don't know any guides off the top of my head.
Not on my laptop at the minute but once I'm downstairs I'll give you a quick run through of what to do to delete that folder. Might not work, but then again it might

Hey mate thank you very much.
Please dont rush as i am just leaving and will be away for a couple of days. I will get onto it as soon as i return.
Many thanx

it won't let you rename or delete because they reside on googles servers, that's why they are showing 0kb. u can't change permission because it's on sd card and w don't have the ability to do so on sd card. i promise a format got rid of them but u didn't notice it because google cache server put links back as your phone started. the explorer crashes because as fast as is trying to remove them the server is already putting them back. basically what im trying to say is just ignore them cause there not really there anyways.

as above, these files seem to be causing problems.
my google currents folder has a lot of these folders, but none of the files are empty.
although having said that, it may be an idea to deselect the option to have google back up your app data.
i'd also maybe try installing the currents app then (if you can) go into the app settings and clear the data.

that thread gives a good guide to getting adb installed, and gives a good grounding of what it can do. it's a bit more in depth than what you need though, all you need is to install it, add the path to the environment vaiables as described in that thread (that is an optional step but it makes things much easier)
the path you'll be looking for is /mnt/sdcard/Android/data/com.google.android.apps.currents
be sure to remember that the case of the letters in the linux (and therefore android) file systems is vital - ie mnt/sdcard/Android is an entirely different folder than mnt/sdcard/android.
so basically once you've your note connected (with the screen unlocked) open a command line and type (minus the quotes) "adb devices"
it should (hopefully) list your note in there.
then type these commands in order, being careful to observe the correct case when typing filenames or folder names.
adb shell
rm -r /mnt/sdcard/Android/data/com.google.android.apps.currents
it could take a while if there are a lot of files. once it's finished, you should be back to a line with a flashing cursor, then just type exit and it should take you back to your standard windows command line.
i would try taking off the "back up my settings to googles servers) and installing currents and wiping the data first though.
OK time for an update.....
Aroma file manager same as all the others, it either freezes or crash's out altogether.
I have already deselected back up to google, no effect.
I have already tried re-loading google currents and populating it with fresh downloads. Then clear data and un-install, no effect.
Finally took me a while to get adb set up and working, but............
wait for it............................................................................
No effect !!
It starts the process, and scrolls info very fast. I left it for about 20 mins and it was still going. eventually i clicked on the window and it said something along the lines of no such file or directory then endlessly scrolls att.
I appreciate the suggestions given, but i do hope there are some more.
I am completely lost with this now.

Seems kind of similar to problems I used to have in the good old Palm OS days, sometimes due to some app errors 0b files would appear on SD card, and - to make long story short - the only thing that would help was taking the card out and formatting it on the computer.
Maybe flashing with repartitioning could help?

If you cannot delete the folder with del or erase command in dos I think you have a bad block there. In this case you have to leave this folder alone.
Hi, thanx for the further suggestions
tknguyencsu leaving alone is not a good idea as it does affect how the note works. Anything that scans the int sd freezes or crash's out when it gets to that folder. for instance if i go to manage applications it will only give me detailed info on apps from A to C any after that it wont display the size of data etc, just stays on 'computing'. so i really need to get rid of this folder.
p107r0 Any idea how i try your suggestion of 'flashing with repartitioning' ?
I have done several full wipes inc usb storage, i have formatted usb storage from recovery several times also.
There are a couple of options in recovery i have not tried because i dont know what they really mean and so im a little scared to try with all the bricking thats been going on.
many thanx

Lots of reading to be safe, but afair there is Dr ketan's guide on flashing LBF with repartitioning, which should be theoretically safe when performed from/over GB ROM. I'll look for the link later.
Here.
P.S. There's also app by chainfire which checks if your device is prone to superbrick: Got Brickbug

Thanx p107r0 i've had a quick look/search in that thread. Not much detail about re-partitioning, i am now assuming it is connected with pit file ?
If that is correct then i have tried that and unfortunatly it did not help.
I am out of my depth here, so if i have misunderstood please forgive me, and enlighten me.

Are you still on the same ROM? Maybe formatting int sd from other one would do the trick?
Hi p107r0
Yes i am on the same rom, but now a later version.
I am using Rocket Rom. the problem first came to light after upgrading from v1 to v2. since then i have been back to GB to RR v1, RR v2 and am now on RR v3.
I am out of time tonight, and on the road all day tomorrow, so will try a completely different rom as soon as i can.

[Q] Deleted root folder (/, not /sdcard)

Update 2:
So now I can see most of the files with ES, but OI file manager isn't seeing them. What the heck is going on? Ghost files?
Alright, so I'm in a bit of a pickle.
I was having problems with Rdio and wanted to wipe all traces of it from my phone to install an older version. Using ES File Explorer, I searched for all the files related to the app in "/" and once I found them, I foolishly used select all and delete. Problem is, it seems "select all" actually selected all the folders in / and not only those found using the search function.
The odd part is I can see all the folders in / when I use OI file manager (though some are empty, namely /data and /datadata), but not when I use ES.
Does anybody have an idea as to what I can do? Odd thing is the phone is working fine and not all files on it have been deleted (the files inside EFS seem to have been though, but I still have signal). I'm afraid to reboot it since I figure it might become bricked. I've got a recent Nandroid backup which wasn't deleted, so I'll be fine if I can get to recovery, but is there any chance of that not happening?
Anyways, I'm feeling really dumb and stressed out.
Thanks for looking and/or helping!
Cheers!
Update
Making a call seems to have restored the files (.bak and others) in the efs folder and some other files seem to be reappearing. Maybe if I just wait it out all the files will come back from the dead? Files that weren't showing 10 minutes ago are back and are dated earlier than today.
Again, I'm mainly looking to know if I can reboot into recovery (or normally?) without many problems.
Thanks!

[Q] Cannot exclude folders from Album app

Hello,
Can anybody tell me how i can exclude some folders which contain images from showing up in my Album ?
i found a few replies regarding this in other forums but none of them worked and I tried asking in talk.sonymobile.com but it was useless.
I tried the .nomedia file creation method, Quickpic method and adding dot to the folder name method.
I tried all those methods to prevent the pics that i get via whatsapp from not being shown in my album. As you may know the pics that we download via whatsapp gets stored inside "Whatsapp images" folder.
I tried to put a blank .nomedia file into the folders and then cleared cache and data of both Album app and Media storage. Then after doing all that i rebooted my phone. I can still see the pictures in there in my Album app once i add a new pic into the folder.
Am running .253
i would really appreciate it if anybody could help me out :angel:
I am 100% positive that there are many people who would love to have a solution for this.
If you need anymore info then do please let me know.

the .nomedia way worked for me. but the trick is cleaning data and cache of the media server/media storage (don't know the exact name at the moment) in settings->apps, and then restarting the phone.
after a restart, album will be empty and start rescanning your storage. when finished, you'll see that there won't be the .nomedia folders included anymore.

Resetting phone usage statistics: data and process stats

Some are asking how to reset phone usages without formatting data.
here's what I am doing just to reset my usages:
I'd say much better if your phone is rooted, and a nandroid backup just in case there is something wrong on what you've done.
-Must be rooted and must have a root capable file explorer/manager.
On internet usage:
open this folder in /data/system/netstats/*
inside that folder, delete all files. DON'T DELETE THE FOLDER ITSELF.
it will cause bootloops
On battery usage:
delete the following inside /data/system/* : batterystats-checkin.bin , batterystats-daily.xml, and batterystats.bin
On process stats/usage:
inside /data/system/procstats/* , delete all files inside that folder, again don't delete the folder itself.
also open /data/system/usagestats/0/* , delete all the files inside the following folders: daily, monthly, weekly, and yearly.
not do not delete the folders. might cause bootloops
After that, reboot normally. after rebooting, you will notice that usages are back to its lowest values.
I hope it helped for some who has problems regarding phone's usage.
This section is for device development, post it in general section.
Sent from a Device using an App!
delete them all but the data remains previous after rebooting....
Does anyone ever find another way that works pls?
There has to be a way to reset phone usage/app usage time stats, i tried lotta stuffs on the internet but on dialing *#*#4636#*#* i get the same result
