Excellent file utility from the Robot PD library.
Like AnsiTerm and DosCopy as soon as this was released the CPM equivalents were made obsolete.
See this post for an equivalent CPM utilty:

Using Columbia one 10K text file is compressed to 5K and, using the "multi-record" option, twenty one various
text, BASIC and binary files (totaling 108K) are shown compressed to one 60K "library" file.
