NuFX (NuFile Exchange; also known as ShrinkIt format) is an archiving format that was used for the Apple II series late in its history. It was created by Andy Nicholas as a student project at Moravian College in Bethlehem, Pennsylvania. The ShrinkIt program (also created by Nicholas) supports it. It usually uses LZW compression.
When NuFX-format data is placed into Binary II format for transfer, the file extension .bxy is used.
NuFX also supports storing disk images. Files using this feature typically have extension .sdk.
