The program generates a catalogue of the files on the cartridge selected by the user, reads the catalogue into memory and erases the cartridge copy, so that an up-to-date copy is always generated.

BBCFiles is a BBC file converter that converts between some of the various types of files used by BBC emulators on Acorn & PC formats. It supports 6502Em style applications & scripts, /ssd dfs disc images (supporting watford double catalogue), vanilla directories, /zip of bbc files with /inf files (with limitations) and directory of bbc files with /inf files.
2003, "Brotha G", Repairing Microdrive Cartridges (on newsgroup comp.sys.sinclair)
It has two extra options using extended syntax. CAT - an extended catalogue but not as detailed as some I've seen. ( The reason that the Spectrum CAT command is restricted is that it cleverly uses the 512 bytes data buffer of the microdrive channel to sort the filenames - hence the limit of 50 ten-character filenames )
