SPLIT (M. Dingacci)
SPLIT is a file splitting utility for DOS, developed by M. Dingacci. It creates raw file fragments, so it doesn't have a native file format.
Fragments are given filename extensions .001, .002, etc.
If SPLIT is used to re-join the fragments, and the original filename extension is unknown, the default extension .RE$ will be used.
SPLIT has an option to store a CRC integrity check in a "control file". But we've had no luck getting this feature to work, and the documentation says nothing about the format or name of the control file.
The documentation says that "SPLIT480 (01-15-89)" was the first public release, but version 4.76 (ca. 1988-06) is in some software collections.
