- Button that creates '.bak' backups for any number of selected files.
- If a .bak already exists for a file, it will create .bak2, .bak3 and so on.
- Works even if each selected file has a different number of .baks already
- Allows changing .bak extension to anything (See 'backupExtension' variable)
Example Result:
