Catfish is good and is on my system, but another good one is VI Directory [free at www.visual-impact.net]. VID reads your archieve listings and allows you to make a print-out of the file names. The printout allows you space to make notes on the files and makes a very efficient index of folders/files on your harddrive or archieved CDs. As to keeping thumbnail files I used to use Thumbs+ but this is just added clutter to harddisk or archieve space. If I need to see graphically what a file contains I just do a look-see in P3dO Explorer.
