NuFX archive is an archive file format that supports lossless data compression that is given the file extension ".SHK". A NuFX archive or .SHK file may contain one or more files or directories and with the extension .SDK even contains entire floppy disk images. This format actually specified via the NuFX file format, was meant to replace and "Binary II" format back in the 1980s which had the .BNY or .BQY extensions... file envelopes with no compression. The .SHK file format permits a number of compression algorithms. This format was originally created in 1980s by Andy E. Nicholas and was first implemented within his ShrinkIt utility.

History
Andy E. Nicholas created the NuFX file format including compression to update the "Binary II" format that had an extension like .BNY and created a pkzip like program called ShrinkIt for "Apple II" systems that eventually migrated to the Apple IIgs as GS-Shrinkit.
This was the de facto Apple II file archiving format and method.
Version history
Andy E. Nicholas, created Shrinkit program which transitioned the apple .BNY format to move on from old Apple IIe/c computers with 128KB of memory to the next generation Apple IIGS computers and a new GS-Shrinkit program.
Both programs developed by Andy E. Nicholas, the Apple II ShrinkIt was ultimately 3.4 and GS-ShrinkIt was ultimately 1.0.6.
