Super 128 Warez Filer v3.0 by Albert Wiersch (October 17th, 1989) - Supposedly, this is one of the best software cataloging utilities made for the Commodore 128 (80 column mode only).  It can support up to 1500 titles in memory (1400 if you want to use sort) and has all the major features you'd want or need to save, edit, sort and find the software you have saved on those 2500+ floppy disks.
