Quarktory by Dan James - QUARKTORY will print a two-column directory to the printer, the screen, or to both.  QUARKTORY is an advanced directory lister in that it not only prints the filename, filetype and file length of each file, but also the track and sector of the beginning of the file on the disk and the locations in hex of the first and last bytes of the file when it is loaded into the computer's memory. Having this information at hand at all times can be very useful in investigation and understanding your programs.

QUARKTORY can be used with the C64 or with the C128 in 40 or 80 column modes. The drive can be a 1541 or a 1571 using single / double-sided disks.
