DSAP displays a report such as this on your home terminal, and sends it to the spooler:
Listing and Purging Old Disk Files
You can make more disk space available on your system by purging or compressing
files and subvolumes.
The Disk Compression (DCOM) program is useful for compressing, or consolidating,
disk space, and it can free significant amounts of disk space for users’ files, applications,
and processes.
You can make additional disk space available by analyzing the subvolumes and files
contained on a disk and selectively purging old files. Also, when system users move to
another system or leave their jobs, their files might be unneeded. Check with the
managers of such users before you purge any files.
1. Determine whether old files exist on the disk.
a. Log on as a super-group user (255,n).
b. List all the subvolumes on a disk:
