'''CRUSH''' is an file archiving utility for DOS. It was developed by Jeff Rollason and PocketWare, and distributed as shareware.

== Disambiguation ==
Not related to the "crushed" compression used by [[PAK (ARC extension)]].

== Discussion ==
CRUSH writes files to its native uncompressed .CRU archive format, then uses an external compression program, such as [[ZIP|PKZIP]], to compress the CRU file. The theory is that a single large file usually compresses better than multiple small files. CRUSH tries to order the files so as to optimize the compression ratio.

CRUSH can optionally create and use an index file (.CRI), outside of the compressed archive.

== Identification ==
Files apparently start with ASCII "{{magic|CRUSH v}}", and have {{magic|0x0a 0x1a 0x00}} at offset 10.

The 4-byte integer at offset 22 has value 26 ({{magic|1a 00 00 00}}) for CRI, and a larger value for CRU.
