Cathy Catalog File

A CAF file may also be a catalog created by the Cathy media cataloging tool. It contains an indexed catalog of media files that users can search through within Cathy. CAF files can be shared with other Cathy users to allow them to browse your media collection.

More Information

Cathy is a free media cataloging program that music and movie enthusiasts can use to catalog the CDs, DVDs, .MP3 s, .MP4 s, and other media that they own. When a user saves a catalog within Cathy, it is saved as a CAF file. After creating a CAF catalog, users can search the catalog by filename, the date a file was created, or file size.

Sometimes, Cathy users share their CAF catalogs with others, allowing those users to peruse their media collection. Note that sharing your CAF catalog with someone won't allow that person to actually play your media. However, it will allow you to compare the pieces of media you own (and maybe, inspire you to swap some files).

How to open a CAF file

You can open a CAF file in Cathy. To do so, place your CAF file in the same directory as your Cathy.exe file. Then, open Cathy. Your CAF catalog will appear in Cathy.
