Apple Logic Pro 9 - Manual (Page 619)

Logic Pro updates the path information for all open projects that use a given audio file.
This makes projects easier to manage when moving audio files. After you move files to
a new location, save each open project to update all audio file storage references.
Warning: Be very careful when using this function as files are removed from their original
location. Other projects may use the same audio files. This can lead to you being
prompted to search for the files that were moved when opening other projects (see
Finding and Replacing Orphaned Audio Files ).
Copying or Converting Audio Files
You can create copies of audio files in a different hard disk (or other storage medium)
location. The source files remain in their original storage location (unlike the behavior
when the Move File(s) function is used).
To copy or convert audio files in the Audio Bin
1 Select the file or files.
Note: You cannot use this command to convert compressed multi-channel files (AAC,
ALAC, MP3).
2 Choose Audio File > Copy/Convert File(s) in the Audio Bin (or Control-click the Audio Bin
or use the corresponding key command).
