[APP][4.0+] Secure Data Destruction - Android Apps and Games

Secure Data Destruction for Android is a tool to destroy files so they can not be recovered.
It will overwrites the actual content of those files, so a file recovery app may be able to restore these files but the content will be destroyed.
You should used it to destroy sensitive files before selling your device.
You can:
1. Wipe files: you select one or more files with the checkboxes and press the trash icon. The selected files will be overwritten. After the files are cleaned, they will be truncated, renamed and then deleted.
2. Wipe free space: press the card in the list that you want to wipe. You can choose between the internal memory, an external microsd (FAT) or a USB key (FAT). After a confirmation, it will be filled with temporary files until the card is full to overwrite previously deleted files. These temporary files will be deleted at the end of the operation.

New version with:
a Material Design interface

selection of files from a files manager or gallery was added
an option to clear files in cache before wiping free space

[Q] Moved Chrome to SD Card and broke it

I have a Sony Xperia C2305 with Android version 4.2.2.
I was trying to free up internal space using Titanium Backup Pro by moving applications over to the SD Card.
I converted Chrome to a user application and then moved it tot he SD Card.
When I run it i now get the following error:
"Critical functionality required to run Chrome is missing; either your Chrome installation is incomplete or not compatible with this version of android".
I attempted to do the following:
- Moved back to Internal Memory and Converted to System Application - Same Error
- Rebooted - Same Error
- Converted to User Application & Uninstalled - Downloaded from Play Store - Same Error
- Converted Downloaded & Installed Chrome to System Application - Same Error
**How can i get a working version of chrome back on my phone?**
Try this:
Using Root Explorer, make a copy of your original Chrome apk and delete it from system/app folder.
Open Titanium Backup Pro, press menu then Clean up the dalvik cache. You will be prompted to delete a file.
After deleting the file, restart your phone. You should be able to install Chrome from the Playstore normally.

TWRP backup including internal storage

We all know, at least I hope so, that if you perform a backup in TWRP the internal storage data (photos, documents, etc.) is not included in the backup.
https://twrp.me/faq/backupexclusions.html
Of course, you can always manually backup the internal storage. But it is possible to include the internal storage data in a TWRP backup by temporarily renaming the media folder inside the root folder data.
A TWRP backup includes the TWRP folder for it is part of the internal storage. Therefore it will also backup all the large files which are present. It is therefore more convenient to keep the TWRP folder as small as possible, but it is up to you.
1. Go into TWRP recovery.
2. The path is button advanced button file management within the data folder you will find the media folder. Rename the media folder
temporarily to e.g. ABC.
3. Perform a new backup in TWRP and give it a new name. Don't leave TWRP but enter file management again.
4. You will find a new media folder. This is because TWRP creates this media folder, it includes your new backup.
5. Your follow-up actions will be to rename the new media folder into e.g. DEF and rename the temporary folder ABC (which is the original media folder)
back to media.
6. Restart your system and now you find a TWRP backup including internal storage in the DEF folder. Move this backup to the TWRP folder and delete
the DEF folder.
Thats it.
Do not forget when you perform a recovery with this backup to repeat step 6.

OK I found another post, using same method but used examples.
Indeed they are using same method,
and I would like to thank OP and that post's OP.
both help to "include internal storage into TWRP backup".
thanks~

--------------------------------------------------
Can you write in more simple english?
I really dont understand the details.
It will help with examples, with the full path instead of just "ABC" "DEF"
Thank you.
Good looking out OP. Never know when I may need this. :good:
a very good guide
you can always use
thanks for your effort! if you like you can test my solution
Universal-TWRP-Bind-Mount-Enabler.zip (do not flash!)
Thanks mart56, I am looking for this for some time and now i got right solution. it's really help me with internal storage backup.
Excellent
If backing up to external SD Card, media directory is not created, so just rename it back after the backup process. If rebooted without renaming back, then it recreates media directory.
.
I was looking for full back up solution and found this: https://www.xda-developers.com/tipatch-patches-twrp-full-data-backups/
Both options have drawbacks... I dont like wipe data option in TWRP to delete data including storage .

As I understand our media should be back up in ABC. So during recovery after "format data" or "wipe including internal storage" it will restore our media in ABC folder, do we need to rename it back to media using TWRP to complete recovery?
My understanding is that internal storage will stay in ABC, and not be visible when boot in System(not doing step 5). In system we will have the newly created media empty (because we can not do step 6 DEF folder is actual internal storage and will not be included in back up).
So do you mean that we need to do step (5) after recovery? Not step (6)?
useless
whenever i tried to take a backup,the same error pops up,even after following ur instructions.so ur post is useless for me.
Guys, does anybody know, why twrp doesn't see an option data including storage (large sd needed) while I am trying to restore it? It definitely is present in the backup
I followed this guide and the backup size is 28591MB (boot, data, system). However, the internal memory of my S4mini is only 8GB. How can the /data/media folder be bigger than the internal memory? It is not stored on the external sd card is it?
UPDATE: I deleted the /data/media/0/DCIM/.thumbnail folder and now the backup is only 4950MB
V helpful and useful tip Thanks

Empty directories

Hi. I need to find all empty dirs in the specific dirs, so I started google that question and found following:
1. "find" on android doesn't work with "-empty" arg.
2. Google shows me some play store apps, which should find empty dirs, but they delete ALL of them right away on the whole system (or Android dir) and some of them can't even see SD card, but in my case I only need found them only, not auto delete.
So how one can find all empty dirs on android ?

I use an app called "Empty Folder Cleaner" on Google Play store. It's never deleted a folder that couldn't easily be re-written by a seldom used app. Been using for over a year now with no problems. Ad-Free, too.
Only catch, is you can't do your SD card w/o root access. Internal storage works fine though, (non-root)
Description by the app publisher;
Annoyed with loads of empty folders in your file manager? Use this app.
Key Features
1)Multiple options to delete empty folders
2)Delete empty folders from internal storage(No root required)
3)Delete empty folders from external storage/memory card(Root required for this feature only)
4)No advertisement
With a single click all the empty folders will be deleted.
Options to delete empty folders
1)Show progress - get the progress of which file is being checked for empty folders
2)Log deleted empty folders - get the list of all the empty folders deleted
3)Scan ANDROID created folders - will not delete empty folders from the directories /Android/data, /LOST.DIR, /DCIM
Note: folders with ".nomedia" and other hidden files will not be deleted as they might be required by the system or the app which has created it. Developer is not responsible for any problem created by the app. You use the application at your own risk

Yes, this is one of the apps I found, but it is not what I need, as I said in the first post.

A doubt regarding cache

I basically use my android file manager ... Recently i found out one thing... If i capture few photos from camera app or download few photos from websites and view them from my file manager ... The File manager cache storage increases...
I can understand that it creates temporary files to make the photos load faster the next time (around 10mb) but my doubt is
I deleted all my camera photos and cleared the recycle bin in my file manager ... But still the file manager cache storage is 10 mb... It is still in the cache space...
I know the deleted images will be taken out from normal file list but still it will be there hidden
Until rewritten by some other thing ..
But my questions are
So does the deleted images stored as cache in the file manager ????
Or is it just useless after the original image is deleted??
Without using recovery softwares, will the original image be recovered with this file manager cache??
Kindly give an answer with detailed explanation
Each app, so also the File Manager app you use, has its own cache where the app is storing files to reference later. If the File Manager app currently doesn't have a setting for how much disk space the cache is allowed to take up, so it just keeps getting larger and larger until the entire drive is full.
Whatever data the File Manager app stores in its cache, they aren't accessible by any recovery softwares, AFAIK.
