Making space for new CC

[morphius1]

It is time for me to delete some custom content. There's some things that I don't use in my games anymore. My problem is that I need to know what I am deleting. I tried the CC Majic. It works by letting me see what the CC actually is...except I have over 600 package files and CC Majic would only show a quarter of them.
I need a mod or something to show me pictures of the files.
Yes, I have been to WCIF and got no response...got tired of waiting.
Thanks.

Try TSR (http://www.thesimsresource.com/) (TheSimsResources) they have a program called Merlin, which can show pictures if there is any in the package/sims3pack, one other i can think of is CasTextureUnitool, though it's for cloths mainly and can only open if there is a caspart (mesh) in the package.
There is also s3pe which can open any package file.

Other then that it's trial&error method i'm afraid, remove a few and check what's missing in game.
