When we use a computer, we inevitably encounter problems with reinstalling the system, and then we will encounter another tricky problem - how to back up important data? I will share some of my own experiences.

Backup and recovery tips for "My Documents":

1. The most original method: Copy all files under "My Documents" to a removable disk before reinstalling the system ( Move the hard disk) or other places outside the system disk, and then copy it to the new "My Documents" directory after the system is reinstalled;
