It's been too long to remember, but I recall that there were a number of runtime directory management applications. I'm looking for recommendations as to which one is best (pay, free, don't care, but free is better :) ).

To boil it down, I have a humongoid runtime directory (basically, everything from 2001-2005) that I'd like to collect parts from and move to separate runtimes (e.g. take all the Milkids stuff out and move it to a separate runtime, all the SP3/Aiko 1 stuff, etc). I figured it would be faster to do it this way than to comb through zillions of backup DVD's, website purchase records, and sundry (not to mention the gobs of freebies that can never be located or downloaded again).

So let me have it - which one do you recommend, where can it be had, and if it ain't free, how much will it cost?
