For security reasons, Jalopy creates a backup copy before it overwrites a file so the file may be restored in case a severe error occurred during the write process. The original file is stored in the backup directory and normally removed after the newly formatted file has been successfully written.
Level
The backup level defines how many numbered backups should be retained (up to 30). The default is to never keep any backups (i.e. the backup level is set to '0'). Use the slider to set the number of backups you want to keep.
Directory
Specifies the directory where file backups are stored. You should leave this setting untouched in order to make your code convention portable across different systems and platforms (See the section called "Exporting" for more information about possible portability issues).
To change the backup directory, click on the button. A dialog appears that lets you enter a new directory or in case the backup directory was already changed, select one from out of the last 10 chosen backup directories.
