Windows deletes files in two ways:

1. Delete normally, that is, after selecting a file, press the Delete key on the keyboard or select the Delete option in the right mouse button. Ordinary deletion just puts the file into the recycle bin, and any deleted file can be recovered in the recycle bin, which is equivalent to the "regret medicine" after deleting the file by mistake.

2. Delete completely, that is, press Shift+Delete after selecting a file, and the deleted file will be deleted directly from the hard disk partition without moving to the recycle bin.
