PIM / PIMPLE is a high performance compressor by Ilia Muraviev. The names and the formats conventions used are somehow confusing. AFAIK, PIMPLE is the compression engine and the name of the first compression tools using it, while PIM is the name of the later multi-file archiver. There are two version of PIMPLE format, PIMPLE1 and PIMPLE2. Also, there are two version of PIM format: the first consisted in a concatenation of PIMPLE files, the later introduced a new format with a different header.
