ARQ is a compressed archive format, apparently associated with the Crusher data compression toolkit by DC Micro Development. It is supported by a DOS program named "ARQ Crusher!".

The format was apparently used by several installer programs, notably Setup Factory by Indigo Rose, whose packages may include an ARQ-format file named IRDATA.IRD.
