Saving Projects
When you choose File > Save (or use the corresponding key command, default
assignment: Command-S), the current project is saved with its current name intact.
If you don’t want to overwrite the most recent version of the project file saved with this
name (which will happen if you use File > Save or Command-S), make use of the File >
Save As or File > Save a Copy As commands. In the dialog that appears, you can enter a
new name for the project, set assets, and select a new directory or even create a new
folder.
• File > Save As: The next time you save using the straight Save (Command-S) command,
the new filename and path are used. If you use this command to save your project to
a new location (outside the current project folder) and select the Include Assets
checkbox, the new project folder will contain all audio files used in the “old” project’s
Arrange area.
• File > Save a Copy As: The next time you save with the straight Save (Command-S)
command, the existing filename and path continue to be used. The copy is a replica
of the existing project, stored in a different location. It does not update the file save
path. Save a Copy As is ideal for archiving and moving data.
Automatic Backup Files
When you save a project, Logic Pro automatically saves up to one hundred backup copies
in the project folder’s Project File Backups folder. The backup files are named after the
project file, with the number (00, 01, 02, and so on) appended to the project name.
