How do I render 61 individual files?

Okay I picked up this Robin Trower Signature Licks book and disc and the disc has got 61 tracks on it. I tune my guitar a half-step flat so I'm not in tune with the disc. It would be neat if I could render all 61 tracks on the disc a half-step flat and then create 61 new individual files. I know how to pitch adjust already as I've done it before but how do I render a bulk selection of tracks like this? I would like the tracks to be labeled as Track01, Track02, Track03, Track04 etc... I know I could manually select each track one at a time and then say add to render queue but that means I would be doing that 61 times and I figure there has got to be an easier, more automated way to tell Reaper that I want it to render 61 individual tracks labeled as above.

Well I think I found a way to accomplish what I want but the only bug is that Reaper has its own numbering system which I gotta fix.

Okay I got it figured out using Wildcards. But the problem is now that my folder of newly rendered files is way too big. It grew from 600 MB to over 2 GB. And Reaper made each one of my files about 49 MB. Not sure why it did this?
