Storage Audit Software

I was wondering if anyone knew of good software for auditing a network share with the intent of reducing used space. I want to be able to check for duplicate files, files over a certain size, files of a particular type, and even just a breakdown of which folders/subfolders are using the most space.

I know I can do all of these things using a variety of tools including the integrated Windows search function for some but I’m looking for more of a comprehensive program that does most of these at once and might even have options for searches I haven’t thought of to help reduce storage.
