I installed CM10 on my GS2, and during the process I didn't format the file system as I wanted to retain my photos and music on the device. I was aware of an app called "SD Maid" that is supposed to be able to be able to clean up all these old app folders, but it doesn't seem to work. Does anyone know how I can clean up all these folders, or does a person have to just go in and manually delete all of them?

(For an app to do this, the OS would have to have some sort of a referencing system of known installed files & folders, don't know if it has such a thing though.)

didn't format the file system please clarify? do you mean on SDCard or on the actual /system, if it's the latter then why did you not format it? –  t0mm13b Jan 13 '13 at 3:52
I didn't wipe either the SD or internal memory; in retrospect I can't remember why exactly, but that's what I did. –  tbone Jan 14 '13 at 5:06

If you're changing rom (I.e. from AOKP to CM10) you should always do a factory wipe, data on the sdcard will still be

I'm amazed it booted if you didn't do a factory wipe before flashing a different rom

How do apps like ROM Manager work then if you do an entire wipe each time? (Sorry, I realize there's some fundamental concept I'm missing here.) –  tbone Jan 14 '13 at 5:08
Rom manager will wipe the /data /cache and /system all your pictures and applications that store data on the sdcard are on the /sdcard partition. What exactly is it you want removed? –  spences10 Jan 14 '13 at 10:22
Folders (at least) on /sdcard are what I can knowingly identify as old apps and wanted to delete, but I wonder if I have tons of system files left over from the stock OS. –  tbone Jan 14 '13 at 14:21
I tried to find the guide I used for upgrading but I think it was on the CM10 wiki and has now been deleted (or archived to where I can no longer find it) –  tbone Jan 14 '13 at 14:23
How many folders do you have on the sd? –  spences10 Jan 14 '13 at 16:57

my answer is using the app sd III is all for the good a great application to uninstall and reinstall applications to your phones hardware it clearly cleans up the internal storage by moving vice internal storage to the phones modem and then cleaning every single application and downloadable file you then set your data to transfer to the mobile phones external hardware it really does work and doesn't lose any phone data it's as simple as that and I mean simple.
