Looking for ideas

I have so many files downloaded, it is absolutely crazy! I know I am not alone! I am looking for ideas that can help me make my project idea into a real thing. I want to somehow create a catalog that has an image of each file I’ve downloaded. I realize what a HUGE undertaking this will be. I am not sure what program to use to help me do this. My first thought would be MS Word, but that might not be the best idea. Any thoughts or suggestion are appreciated!
