Question about app 2ext

I have Froyomod v.2.70 on my milestone and an ext3 partition. A part of the apps moves to the ext partition, but I thought that everything would move there. I cant see the ext partition in settings. I thought ext partition would be an extension of nand. Do I have to do something before this works?

apps2ext works out of the box on FroyoMOD. I am not sure about ext3, but it works perfectly with ext2. All your data apps should move to the ext partition. You cannot access your ext partition information from within the phone.
You need to use a pc for that.
Edit : You can also check your /sd-ext folder using root explorer.

I can find the apks in data/app and in /sd-ext/app, is this usual?

Not in data/app, check in root folder under sd-ext.

The apps are in /data/app and in /sd-ext/app. If I delete an app in /data/app its also deleted in /sd-ext/app.

Since app2ext was successfully enabled on the Rom,..does it still need "moving app to sd" on CM's menu appliction setting?

No need. Apps2sd is very different from apps2ext.

I have only 86mb data storage left. This means not everything moved to ext.

as i remember, froyomod keep cache

In the description of FroyoMod it is said, that dalvik moves to ext. But i cant find dalvik-cache in sd-ext via root-explorer. My internal storage is nearly full.
Sent from my Milestone using XDA App

As far as I am aware, app2ext only moves your apps (.apk) to the ext2 partition. However, dalvik cache and data from apps still is on the internal storage. It means your data/data folder cannot be moved to the ext2 partition. That's why you still have little space left even if your apps are not on the phone.

Hi all,
so is there any way to move dalvik cache to ext2 on FroyoMOD?
i'm now using FroyoMOD 2.8, everything works great except my internal storage is almost full because of dalvik cache.
thanks for your help.

Install and uninstall apps will cause residue files in system memory?

If we install/uninstall any apps, will the uninstall really clean/delete all the files from the system memory? For PC software sometimes it leaves something in the registry key or system directory.
Will Android has the same issue?

althou android doesnt have a registry.. i have seen that some apps leave their custom folders and files in the usb storage... which i have to find and delete manually.. mainly games and other apps that download data after installation

I'm also interested to know about this too...with Windows I'm pretty careful with what to install as I don't like too many un/installs...curious to know how Android handles many un/installs...

Based on my experience there are many leftovers even after un-install. One suggestion is to use the 'Clear Data' button before uninstalling an app. However, even after this there will be leftovers esp in the sdcard\Android folder.

Left over under Android folder still manageable, my worry is it left something in the restricted folder where we have no access unless we root. Is matter of time run out of internal memory until factory rest.

it depend on what kinda that you use. some apps will left empty folders when you uninstall it.

same here
I actually have the same worry with my phone since I keep on trying different apps.. I just "clean data" and "clean cache" for the app before I uninstall it and I dont have problems with that..

The tool that I use is SDmaid. It helps me in identifying leftover folders and app debries. You can automatically delete them using the app.
Worked fine for me.

I tried SD Maid, it did help to free out at least 200+Mb of internal memory. Cool..

Most of the time, the biggest "trash" SD maid cleans up is the Gallery thumbnails..
Soooo when you startup your gallery app again, it regenerates the thumbnails so youre back to square one.. LOL

I am referring to internal memory, it freed up about 200+MB from program cache. Correct, the thumb view file (another 200+MB) from gallery reside at sd card will rebuild after delete.
Funny thing is wipe cache at CWM won't free up the internal memory.

I've noticed on ics that games and some apps leave folders on the usb storage. Gb used to remove them..

For a specific case...
phone had installed the free version of AutomateIt.
Uninstalled it by: "clear cache", "clear data", force stop", and then "uninstall". Then rebooted phone.
A bit later searching the storage noticed a "AutomateIt" folder in Device Storage.
The AutomateIt folder contains a subfolder "Backups", which contains 3 files (all .AiR files). (two are 1kb, one is 0kb) .
Is it safe to manually delete these files and folders?
Are there any apps similar to SDmaid but for unrooted phones? (no root yet for Atrix HD, so not even an option)

Some apps leave behind files or folders no matter what you do. I just manually remove them using a file explorer.
This is my observation. Hope this helps.

Question for Internal SDcard

can the internal sdcard with the Data partion merge so that the data has 8GB instead of 4GB?
I do not know if that is so you can then make the ExtSdCard to internal sdcard??

If it could be done I think someone would have posted the guide already.

So mean my 2 partition can not merge with android devices??

I have plenty of apps and data stored in the system partition. But it would not be wise to use it all up as system uses that free space for caches and processing. Filling it up would make apps run slow.

Using a root explorer, check the total size of your /data and /sdcard partition(In ES its long press > properties). How much space are they taking up? Also, have you checked in /data/media for duplicate files?
Also, ES File Explorer has the ability to list all the biggest files on your /sdcard so you can see what's taking up space.

have root? if so get root uninstaller.
i don't remember those apk's specifically tho. not sure where you got that stuff. do you know what it is?

You've been visiting naughty sites!
Try force stop before uninstalling.

Daily motion, lucky patcher, etc. I tried to force stop before uninstalling and that didn't work. No naughty sites.

Looks like these are on your SD card. Did you try backing up internal storage, removing external SD then delete? Might have to do some SD house cleaning!

No I haven't tried that. What would be the process?
Sent from my SAMSUNG-SM-N900A using XDA Premium 4 mobile app

Backup internal storage to PC, then go to settings/general/storage and select format SD card. Do the same with your external SD but use a card reader with your PC. Delete the apps again and reboot. Hopefully the rouge apps will not reappear. Then copy the files you know back into internal storage. Try not to over write anything in internal storage unless you're sure you know what it is. Same for external. Format SD card then copy back the files from the backup you made. If you're not sure about a file, don't copy it back to storage. Hopefully this will take care of the issue. It's also good to clean stuff from storage that serves no purpose. Good luck!

If I format my internal sd without backing it up what will I lose? Im not worried about anything on it getting lost.

Everything you see in that directory when you view it on a computer.. You will loose all photos, music, games and any other personal data or apps you have downloaded or installed. You will basically have a new phone with only stock apps and data on it.
