The software lies within System Tools, more precisely Backup & Restore.
From the developer:
Disk Recall is a disk cataloging utility. It creates catalogs of any type of disk (floppies, hard drives, CD-ROMs, Zips, Sy-Quests, AppleShare volumes, etc...). It features an intuitive Finder-like list view for browsing disk contents, and a powerful multi-criteria search engine modeled after Apple's Find File utility of System 8. Disk Recall uses a super-fast archiving algorithm to scan disks 5 to 10 times faster than other Mac catalogers.
