Need help finding software

I’m working on lists of software for the new CDFreaks web site.
Any assist in compiling names of the various wares is greatly appreciated.
I need assist in compiling the lists in the following categories:

  1. file sharing software
  2. test and diagnostic software (already have CDSpeed, CDDoctor)

Please post names of software, and if possible, publisher and URL.

Many thanks for any assist!!
