What Is Error 0x80070091 and How Can It Be Fixed on Windows?

I’m encountering Error 0x80070091 on my Windows PC while trying to restore the system or manage folders, and the message indicates that the directory is not empty or accessible. I’m worried this may be due to corrupted files or improper deletion. What are the proven methods to fix this error safely, and if some important files were lost or became inaccessible during the process, can data recovery software help retrieve them?
