March 11, 2022

This article shows you how to shred files/folders in AOMEI Partition Assistant to protect personal privacy.

Why need to shred files?

After deleting the file, if we do not read or write to the partition, the file data information is still "retained" in the hard disk. Therefore, it is easy to recover the files through some hard disk management tools or data recovery software. Therefore, it is best to delete these private and sensitive files completely to avoid data leakage.

File shredding is to completely erase the file, such as rewriting the area where the source file is located with the number 0 or 1, so that the source file is completely deleted and no one will know your privacy.

The purpose of file shredding:

1.     Erase important/top secret/private files to prevent from being recovered.

2.     Delete virus files to prevent infection.

3.     Forcibly shred files that cannot be deleted.

To shred files

Step 1: Install and launch AOMEI Partition Assistant, and then click "All Tools" and "Shred Files".

Step 2: In the pop-up window, click "Add Files" to add the files you want to shred or "Add Folders" to add the folders you want to shred. Or you can drag files or folders to the window directly.

Step 3: Choose the shredding method.

Shredding Method

There are 4 methods available:

Write Zero: Overwrite all sectors with zeros. It is safe and fast.

Random data (1 pass): Overwrite hard drive with random data. It is more secure than the first one.

DoD 5220.22-M (7 passes): DoD Standard is firstly published in Department of Defense of the U.S. It is much secure than "zero-filling" and "random data filling" and faster than Guttman. Thus it is often adopted by companies and organizations.

Gutmann (35 passes): It overwrites a hard drive with 35 passes. It is the safest way here, but it also takes the longest time.

Step 4: Click "Shred" to begin the process.

Begin Shred


  • If you need to shred all data on a partition, we suggest that you can try "Wipe Partition" feature.

  • System directories and critical directories of C: drive can't be added to shred directly under windows. You can create WinPE bootable media of AOMEI Partition Assistant, and then boot from WinPE media to shred.

  • After files are shredded, some data recovery tools might recover some items. But these recovered files are renamed randomly and show 0 byte, can't be opened.
