I've been using an amazing little tool for years,that now has made porting builds alot easier for me and i thought I'd share
http://www.scootersoftware.com/BCompare-3.1.6.10721.exe
It works great with joojoobee's SuperRecmod and has made it easy for me to keep slot 0 free. It allows me to compare virtually anything,folders, binary,txt,cpr,xml,hex,and now when porting new builds I just compare to my old build and makes file sorting for new ErvKitch a breeze. Once I have everything where I want I can select all the modules right click>explorer>sendto>SuperRecmod all from within beyond compare. The vesion linked to is a 30 day full function trial but is worth every penny for me.
