Aldus LZW is the signature of a compressed file format used for installation by some Aldus software products. It is very similar to Aldus PKZP.
Format details
There appear to be two variants of Aldus LZW: one for Macintosh, and one for PC / Windows 3.x.
It uses LZW compression, possibly identical to TIFF's LZW scheme.
Identification
The first 16 bytes of a file are ASCII "ALDUS LZW 1.00".
