File Copier by Marty Franz and Joe Peter (1987 RSD) - A while back I posted this utility, but it was a hijacked version by some group called TSS/Tango Soft Systems (link).  Now that I've found what is probably the appropriate unscathed version, it's time to give the authors credit.  One thing I didn't catch before is that this copier has support for Warp-DOS which is the same as the 1571 Burst Speed, so use that if you've got the right hardware.  Additionally, there is a nice BAM viewer / editor, and a couple other creature comforts.
