It allows you to quickly open the data fork of any file. It is based on TextEdit so it has a limit of 32K. It is also based on メBuggyEditモ that came with THINK C 5.0, since it already did 97% of what I needed, I figured I would メadaptモ it a tad.
This software is free, I donユt think anyone would pay for it anyway!
It doesn't yet support opening files from the Finder and some other niceties, maybe someone else will add that in to a _real_ data fork manipulation application.
