What is a .cab file?
application/vnd.ms-cab-compressed
CAB is Microsoft's Cabinet archive format for bundling compressed files and installation resources. An MSCF header points to folder and file tables; data blocks may use no compression, MSZIP, Quantum, or LZX, and a cabinet can participate in a multi-volume set.
How to use a .cab file
Use an example .cab file to test MSCF signature and table parsing, member names and sizes, bounded block decompression, unsupported-codec reporting, path-traversal defenses, and comparison with a published member manifest.
