Media Asset Tracker (SO)

If even you only enter a few important logos, or one client's files, or files you want to store but never lose, MAT will prove its usefulness.

When you need to find them, MAT will tell you all about the file, and where you stored it - on a cd, a zip disk, a jaz disk, a tape, hard drive or almost any type of storage medium. You may never use all the features of MAT - you don't need to.
MAT is a really good organizer, but it is much more than an organizer. MAT doesn't use clumsy preview files or make you go through media slide shows to find your files.
MAT works much like the familiar file Explorer in Windows, but it has a very powerful and useful set of features for complete file management, even for files that are in storage.
