File Format
Name LZMA Alone
Ontology
Extension(s) .lzma
MIME Type(s) application/x-lzma

LZMA_Alone is a compressed file format that uses LZMA compression. It may be more commonly known as simply LZMA or .lzma format, but note that it is a file format, and not quite the same thing as the raw LZMA compressed data format.

LZMA_Alone is considered to be deprecated, in favor of XZ. Other LZMA-based alternatives include 7z and Lzip.

Format

LZMA_Alone files have a 13-byte header.

Identification

There is no signature, and no reliable way to identify LZMA_Alone files just by looking at the header. That said, it is common for them to start with bytes 5D 00 00.

The lzmainfo utility from XZ Utils may help with identification.
