1. Don't forget to save the file at all times
At work, no matter what software you are doing, I think you should always remember to press Ctrl+S
2. Active backup
Important files must be placed in at least two storage devices, try not to choose a USB flash drive
3. Organize regularly
Organizing is a good habit
4. Pay attention to protecting private files
Private files must be protected separately and must not be placed randomly
5. Delete carefully
Deletion is a double-edged sword
