Recovering Disk Space

When tracks and parts are erased or deleted, although they can no longer be accessed,
the actual sound files remain on disk as unused files, occupying disk space, and reduc-
ing the time available for additional recording. Likewise, takes recorded using auto
punch in/out recording remain on disk even after a single take has been fixed. The rea-
son being that if the sound files were deleted from disk each time an edit function was
used, over time files would be fragmented, and new sound files would not be stored to
disk in consecutive sectors, which could affect disk drive performance.
Disk space occupied by unused sound files can be retrieved for additional recording
using the Optimize function, which deletes all unused files from the disk and optimizes
the remaining files for optimum performance.
Since the Optimize function deletes all unused sound files, the Undo function cannot
be used to undo the last recording or edit once the Optimize function has been run.
Unused sound files deleted by the Optimize function cannot be recovered. Other sound
files are not affected.
You can check how much disk space (i.e., recording time) is recovered using the Remain
function to check the available recording time before and after running the Optimize
function. See "Checking the Time Remaining" on page 38 for more information.
The Optimize function operates on the currently selected work disk. See "Selecting the
Work Disk" on page 161 and for more information about selecting disk drives.
