Folder cannot be accessed after reloading Windows XP system

After reinstalling the XP system, I found that there are some files in my Documents that are not open, prompting "access denied", but this folder was previously set to private.

Log on to the XP system with Administrator privileges, open Explorer on the system, select Tools folder Options, open Folder Options, open the View tab, and uncheck with simple sharing.

Right-click the folder that was originally set as private, select Properties, and under the Security tab, there is an unknown account, which is the original XP system account. This account can access the folder, but the problem is that the account does not exist, so think of another method.

Under the Security tab that was originally set as a private folder, click Advanced, open Advanced Security settings for CMD, select Change owner to current user, and select Replace child container and owner of object below. Click the Apply button to see a process that takes ownership of all the files and folders in the folder. Then switch to the Permissions tab and click the Add button. In Select Users or groups, click Advanced, and then click Find Now to list the users or groups in this computer below, and select the users who give permissions.

Click OK in turn until you open the Permission Entry dialog box. Select Allow on the right side of full control in permissions to get all control over the folder, and then click OK.

Click OK, and then until you close all the dialog boxes. At this point, the current user can normally access the original private folder, the problem can be resolved.
