[Q] Wiping everything on SD Card

Hi I would like to know if it's okay to delete everything on my SD Card and then flash a new ROM. I want to do this because there are a lotttttt of useless folders that belonged to some apps which I deleted. So is there any problem if I wipe everything on my SD Card? I will of course leave my ROM zip file in it to flash it. But is it okay tho? Thanks in advance!

If you had backedup your apps with titanium backup you lose it all. And when you format your sd-card you lose that Rom you're gonna flash.

Yeah dude its ok. When you flash the new rom it'll create a new android folder for all your system junk.

Does Titanium keep the backups in it's own folder, or in each apps' folder?
So could you wipe everything but the titanium folder, then restore apps that way?

In its own folder, just like cwm keeps your backups in one folder.

I need to clear up my SD card, so I'll delete everything bar that folder.

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.

Another good reason to do a full wipe prior to installing a new ROM!

[Q]Software to view all deleted items during history of your phone?

Hello,
I have already rooted my phone, and installed Titanium Backup from the Android Market, and removed all the apps that I don't use, such as
TImescape, Email, Geotags, etc... and managed to free a lot of memory from both the system ROM and internal memory.
There's many software apps out there like Root Explorer, Rom Toolbox, etc.. that allow you to view all the items in
the internal system, but is there software anywhere where you can install on one's rooted phone, and view all deleted items (photos,
music files, video clips, etc.) during the entire history of the phone since you started using it?
I know when you delete items on your computer, they are sent to a part of the system where it can be recovered with the
right tools.
Thanks all,
and Happy Halloween :fingers-crossed:
Ken

I don't know about such an application.

If I am not wrong, the files on the sdcard that you delete are deleted forever. Like Shift+Del in Windows; you can't see them again. The files in the other directories, AFAIK, are deleted in a similar way (where data is not stored). In conclusion, no, you cannot view deleted files.

is it true? but how if we accidentally reformat sd in quick format mode? is data still recoverable?
Sent from my E15i using xda premium

Its recoverable..
I too formatted my sd by mistake.
But then i recovered the lost data using stellar pheonix data recovery using my PC

Its recoverable as long as the deleted files haven't been overwritten. When you delete a file it doesn't actually get deleted, the memory block just switches from 1 (in use) to 0 (not in use). When you save a file, the system looks for memory blocks that are not in use and overwrites them. Thus as long as you haven't saved anything or used the memory it should be recoverable.
There's an app called 'undelete' or something like that on the Market that will recover deleted files.

[Q] Swap storage partitions?

I have a 32GB sdcard, but gameloft being idiots as usual don't give me a choice to use it. I know of gl to sd but it caused me some issues resulting in me downloading data again. Does someone know how to change sdcard to /sdcard and internal into /external_sd? Its been done on phones such as some galaxy s series so why not us? Failing that can someone point me to a clear guide on how to use gl to sd properly?

You might want to use Directory Bind. Please refer to this post http://forum.xda-developers.com/showthread.php?t=1410262

Ok I binded the obb files for mc4, played great first time, second time I deleted obb file in internal as that's the point, to save space, now I launch the game it deletes the obb from external too and asks to download again, what did I do wrong ?
Wait, I think I get it, when bound, both folders are the same right? So when I deleted the internal memory file I actually deleted the external one. I figured this when I started the download and file shows up in both, correct me if I'm wrong

I don't really remember how the whole binding process goes. As far as I can recall, there's a process where the app copying all the data from your internal storage to the sd card. When it's done, just leave it as it is.
Btw, did you check your the your internal storage space after binding?

umm I think it's possible, but you'll need a class6/10 sdcard, if not you'll get a painful lag

Don't worry I got a San Disk Ultra Class 10

Ok, so go ahead!! and report then

So it's SAFE to move to sd apps not included into the rom. If you want to move an app that come perinstalled in your rom onto your sd card with Titanium Backup you need to uninstall the app you want to move or make the app a normal apk not included into the rom on your sd from the rom itself, reinstall it as a normal .apk if you unistalled it and than move it to sd card. That'all folks
I'll write a little and more detailed guide if you think it's useful
O.P. Is safe to freez samsungapps.apk and samsungappsUNA.apk?
