PixFolio, including its predecessor ShowGIF (also written Showgif), is an image viewer and image file management application for Windows 3.x. It was developed by Allen C. Kempe and (for some versions) Paul R. Hachey.

It "catalog" database consists of a .CAT data file, and a companion .CIX index file. The CAT file contains thumbnail images, and other metadata.

Disambiguation

Note that there are several other unrelated programs named ShowGIF.

Identification

CAT: There's no nice way to identify a CAT file. But it can be identified reliably, say by using the predictable positions of the fields of the first item. For example, bytes (hex) 28 00 00 00 (from a BMP header) appear at offset 374. 0x3a appears at offsets 356 and 359, as part of the ASCII timestamp. Etc.

CIX: (TODO)

Software

There are many versions of PixFolio. Selected versions are listed here.
