LZMA Alone

LZMA_Alone, also known as .lzma format, is a compressed file format that uses LZMA compression. It is sometimes simply called LZMA or lzma, but that can be misleading, because "LZMA" more commonly means the raw LZMA compressed data format.

LZMA_Alone is 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 simple way to identify LZMA_Alone files just by looking at the header. That said, it is common for them to start with bytes.

The  utility from XZ Utils can help with identification.
