There was no further compression added.
You likely have some older "+/- files", maybe from an old set of RealTracks, or a patch update or something. These are names like jz001-2.wma or jz001+1.wma (as opposed to just jz001.wma).

If you point the BB 2012 program to that RealTracks folder, and click-Prefs-RealTracks- Erase Un-Neeeded files, it will erase those un-needed +/- files.

Another possibility would be that you uncompressed some of them to WAV files. If so, there would be WAV files of the same name (e.g. jz001.wav), and those would be un-needed as well (they are needed for the audiophile version though).


Have Fun!
