Chapter 1 Using Logic 59
Automatic Backup Files
When you save a song, Logic will first make a safety copy of the previous file. You can
switch off this function in the Global preferences (Preferences > Global), and also set the
number of backup files that will be made—up to 100.
This function allows you to store up to 100 earlier versions of your song, thereby
retaining a complete record of your song’s development.
Backup files are saved in a backup folder within the Project folder, and are named after
the song/project, but feature the “.bak” file name extension. The backup files
themselves are also named after the song, but are sequentially numbered. As an
example: if the song is called “My Song”, the backup folder will be “My Song.bak”, and
the backup files within the folder will be called “My Song00”, “My Song01”, and so on.
Note: If you want to know what the latest version is, take a look at the contents of the
Project > Backup folder in the Finder, making sure you sort the contents of the window
by date (select “By Date” in the Finder’s View menu with the backup folder open, and
selected). The Finder cannot distinguish between files if they were saved during the
same minute.
Reverting to the Saved Version
Any time you make a mistake, you can undo it by selecting Edit > Undo (Command Z).
If you have made some really serious blunders (as unlikely as that may be), or you
decide that in the 15 minutes since you last saved, your creative efforts have resulted in
material too unpleasant to describe here politely, you may find the File > Revert to Saved
function very helpful. This replaces the current song with the previously saved version.
Closing and Quitting
Closing a Song
File > Close (Command-Option-W) closes the currently active song. If you have made
any changes since the last save operation, Logic will ask you if the song should be re-
saved before closing, to preserve any changes you have made.
Quitting the Program
Choose File > Quit (Command-Q) to leave the program. If you’ve made changes, but
haven’t saved them, you will be asked if you want to do so before quitting (press Enter
to save).
