What is destroying my data? What are the reasons for data corruption?

Right-click on the file, attribute General Advanced to unencrypt it.

I can't copy it, it's hard to understand. There is a problem with the clipboard cache. It's like a virus.

Fainted, you said you had redone the system. Try the following:

1.Log in to the system as "Administrator", click "Tools Folder Options" in Explorer, switch to the "View" tab in the pop-up "Folder Options" dialog box, undo the "Use Simple File Sharing" button and finally click the "OK" button (the purpose of this setting is to find the "Security" tab in the properties dialog of the backup folder).

2.Right-click on a bad file, select the "Properties" option, switch to the "Security" tab in the pop-up properties dialog box, then you will find an "unknown" in the "Group or User Name" column, this is before reinstalling the system, because after reinstalling the system, the SID value has changed, so the system cannot recognize this, which also leads to the file being denied access.

3.First delete this unknown, and then click the "Advanced" button in the security tab, the "Advanced Security Settings" dialog box will pop up, and switch to the "Owner" tab, then you will find that the owner of the file is unknown, of course, it is inaccessible. Next, change the owner to yours, and remember to check the "Replace owner of subcontainers and objects" option below (if you selected a folder) and click the "Apply" button.

4.In the Advanced Security Settings dialog box, switch to the Active Permissions tab and click the Add button to add yours to the Permissions Items list box. In the process of adding, you must be sure to give you the permission of "full control", and finally click the "OK" button to complete the modification operation.

This way, you will be able to access those files without being denied access.

What is a personal secret disk?

It seems like only the encrypted and compressed folders of NTFS are green.

Try to install a maxdos, restart it and enter dos, and select NTFS format that supports DOS in the menu. Give it a try.

Or run NFTSPro after entering DOS
