Well... I have two external 1 TB drives that I use as "masters" once the shows are all running properly. One is carried around with me and used regularly. The other never leaves my bedroom. I keep them as exact duplicates. I guess they're maybe half full or so. The directory structure is something like this:
BEYOND GRAPHIC SHOWS
BEYOND BEAM SHOWS
QUICKSHOW BEAM SHOWS
QUICKSHOW GRAPHIC SHOWS
QUCKSHOW MIXED SHOWS
Pangolin Complete Beam Shows (LD2000)
Pangolin Complete Graphics Shows (LD2000)
Pangolin Complete Mixed Shows
Showeditor Shows
LSX Shows
Spaghetti Shows
Phoenix 4 Shows
LA STUDIO
Moncha Shows
Fiesta Shows
Dunn Shows
Full Length (the hour long stuff)
etc.
Then there are subdirectories for each show with the name and song artist. I also have a lot on HD24 that aren't necessarily on these two drives.
I haven't broken down some of the other packages into "graphics" or "beams" yet but, that's part of my project.
I also have stuff for LaserMax and X-29 or whatever it's called but haven't even begun to look at them. I think I have shows for Mamba and maybe another program but don't have the software.
