Thanks Noel but I had already tried Erase Un-needed files before I wrote this post and it did not erase the WAV files. I had previously performed the Erase Un-needed files when I installed 2011 9 days ago so at least when I accidently decompressed not so many WAV files were created. I now have 299 Gbytes in the RealTracks folder and 37 Gbytes in the Drums folder! If I had not previously erased the un-needed files I would have well over 1 terabyte in those folders.
