Oh, gosh. At my peak, I probably had upwards of 2-2500 levels and tilesets, although I've cleaned up a LOT since then, so it's probably down in the 500-1000 range, both 1.23 and TSF combined (TSF used to carry the vast majority of material until I got this random urge one day to switch to 1.23. Speaking of which, does anybody know where a guy could go if his 1.23 Jazz 2 anims file is corrupted? It's been driving me crazy, since nothing I do seems to fix it.).

Total size? Between 2-3 gigs, I suppose.

And get this. I have exactly 42 levels in my cache folder. Beat that, I dare you.
