It just seems that if I have a huge array of filenames and directories, and I want to compare another huge list of filenames and directories, it takes a long time with an array. Say for instance if I have a list of 2000 elements, and I want to compare that to another array that is 2000 elements, thats 4,000,000 iterations thru loops. Would hashes not be better for such a look up method? Maybe I am just putting to much emphasis on it, and the way I did it before is fine.

There is still a good bit that I do not understand about hashes and seeing 10 different way on how to build them kind of confuse me. ;) But the code I posted above, why is it adding $file to both keys and values of the hash?

Thanks for commenting btw :)
