Disk Drive Operations
Pack
By purging files from the disk and adding other files, you may end up
with blank areas on the disk (between files) that are too small for the
new files you are creating. On LIF disks, the Pack Disk operation packs
the current files together, removing unused areas from between the
files so that more space is available for files at the end of the disk. On
DOS disks, the Pack Disk operation is not available. If you do select
Pack Disk while a DOS disk is in the drive, the disk is not affected.
