Sunzip


 * Not related to the sunzip utility by Mark Adler .

Szip, AKA Sunzip, is a file compression utility and compressed file format. It was written by Michael Schindler. Due to changes in the program, there are actually 3 incompatible Szip formats :
 * the format used from v. 1.00 to v. 1.04;
 * then, the format used in version 1.05X and its subversions (the "X" does not stand for anything; this is actually part of the version number );
 * and then, the format used for version 1.10 (which came immediately after the 1.05Xs ) and above.

Extensions
The author "recommend[s] using .sz for szipped files and .tar.sz or .tsz for szipped tarfiles".

Identification
For v1.10+, Szip files start with.

The older versions of the format have no obvious signature, and are probably not easy to identify.
