Exotic thing. The project seems to be it is developed together with Igor Pavlov, who is the author of 7-Zip (and now 7-Zip also supports LZMA2 and XZ format). Accordingly to Igor Pavlov: LZMA2 provides the following advantages over LZMA: 1) Better compression ratio for data than can't be compressed. It can store such blocks of data in uncompressed form. Also it decompresses such data faster. 2) Better multithreading support. If you compress big file, LZMA2 can split that file to chunks and compress these chunks in multiple threads. Clearly XZ is not very popular yet, but I would not call it as exotic. At least, I expect it to be supported by future distributives. Dmitry
