Sometimes it is possible to restore files after you have deleted them. Here’s how to permanently delete android data.
When you delete a file from an Android phone, it remains in your device’s storage area until it overwrites with new data. Unfortunately, this means recovering deleted files on Android using data recovery software, which is a primary privacy concern.
Starting with Android 6 (Marshmallow), all Android phones are automatically encrypted, preventing data recovery tools from accessing their contents. But if you are still worried about sensitive files falling into the wrong hands, we will explain how to delete your Permanent Delete Android Data.
1. Delete Items Using File Manager
The worst way to delete a personal or private file on your Android phone comes from the app concerned. This risks being permanently deleted or moved to the Trash or Bin without syncing to the cloud.
For example, the Google Photos app stores deleted photos and videos for 60 days unless you dump your trash. After that, things will remain in your Google Account even if you leave it by selecting Remove from the device.
The best option is permanently deleting sensitive items from File Explorer or a file manager application. In addition, many free Android file checkers exist, including Google’s unique file system.
Select an item in your File Explorer. Then, click the Trash button, tap the three-dot menu, and select Delete. Ensure you cannot undo a deletion, and then click Delete again. That is how you should delete your files on Android.
2. Delete Data with File Shredder
If your phone encryption doesn’t guarantee data recovery of deleted files or an older version of Android, consider installing a file printer. That will securely “free up” the space containing the deleted data on your device.
File shredders such as shredder, Shreddit, and Data Eraser provide alternative split algorithms. It allows you to set how the data write with random letters. Each override is called a “pass” or “cycle.”
You must allow these apps to access your files (optionally, your contacts, which we don’t recommend), but they don’t provide anything without asking for confirmation.

Here’s how to make deleted data irreversible using Shredder File Data Eraser. Unfortunately, naming it as Android Eraser in the app itself is confusing.
On the Home screen, tap FreeSpace (be careful not to turn it off completely!) and select Internal Storage. The app calculates how much free space to free up.
Press Continue and select the cutting algorithm. The NATO standard and the BSU TL-0342, which make seven and eight passes, respectively, are discreet. However, they also take time.
Make sure you want to continue, and deleting the data will erase all the free space on your phone, so you will no longer have the files you deleted.
Your phone will slow down while the erasing process continues. However, you can leave it anytime by opening the notification at the top of your screen and pressing Cancel.
Although Data Eraser doesn’t charge a fee to clear free space on your phone, you can split up to 100MB of separate files per day for free. Upgradation to the paid version for $4.99 eliminates this limitation.
Credits are a unique free method, but they may block ads and not work on Android 11.
3. Delete Android Files from Your PC
If you do not want to install an application to delete the file permanently, you can connect your Android cellphone to your PC and wipe the data through Windows. This method makes finding and recovering trusted items easy using File Explorer.
Connect your android phone using a USB cable and select Open device to view files in the Autoplay option. Alternatively, open File Explorer, select This PC and double-click your phone’s Drive icon.
If the drive appears empty, pull down the notification tray from the top of your phone screen and select USB transfer or File transfer for this device. Or go to Settings > Connected Devices > USB and open the option.
Browse through your phone’s folder to find the File you want to delete. For example, if it’s a photo or video, it’s in the DCIM > Camera folder.
Right-click the item, select Delete, and confirm that you want to delete it permanently. Remember that the File will not be sent to the Windows Recycle Bin but will be lost forever. This is a solid option if you are wondering how to wipe all your phone data securely.
5. Delete Sensitive Files on SD Card
If the secret File you want to delete is found in the SD card memory instead of your phone’s internal storage, there are several ways to delete it.
First, go to Settings > Storage > SD Card. Locate the File and delete it there. However, this does not make it irreversible, so you may want to format the card. That will completely erase your content, so ensure you have saved any files on your phone first.
Tap on the three-dot in the top right corner and select Storage Settings. Select Format, and then press Clear and format or Format SD card to erase and format the card.
Alternatively, as described above, you can connect your Android cellphone to a PC or insert the SD card into your computer card reader. However, before removing it from your device, you must first “download” it by shrinking or ejecting the card.
Browse SD card contents in File Explorer, locate the File, right-click on it, and choose Delete.
Some Android shredder apps can shred, transform, and delete data stored on the SD card (see Tip 2 above).
5. Restore Your Phone to Factory Settings
The most challenging way to permanently delete private files is to reset a factory. It is best to delete all the data on your phone.
