What is an LZMA file?
File or files compressed with LZMA (Lempel-Ziv-Markov chain Algorithm) compression; used by 7-Zip and other file archivers; known for having better compression ratios than bzip2 (.BZ2 files) and faster decompression.
Some LZMA compressed files can be opened with StuffIt Expander or 7-Zip (Windows) and 7zX (Mac). Other LZMA files may require the LZMA SDK for Windows or LZMA Utils for Unix.
The LZMA Software Development Kit (SDK) is available from the 7-Zip website.
