ZAR is the native compressed archive format of Zip-Archiv, a DOS utility developed by Peter Troxler (sometimes written "Troxler Peter"). Almost all of the information about it is in German.
Zip-Archiv includes a menu-driven version (ZA.EXE), and a command-line version (ZIP*.EXE).

[edit] Format details
ZAR evidently uses PKWARE DCL Implode compression.
To decode a ZAR file, start by reading the 7-byte info block at the end of the file.
[edit] Identification
The ASCII signature "PT" appears beginning three bytes from the end of the file.
The file begins with one of the two-byte sequences that are valid for DCL Implode compression -- refer to PKWARE DCL Implode#Identification.
[edit] Specifications
The file structure is discussed in the TECHNICS.TXT file included with the software.
