Hi. Oh yes, it's certainly possible. We just had another thread about this, although the request was more complicated.

First, back up any songs you have written and any custom styles you may have created, just to be safe.

Is this a Windows computer, or Mac?

Are you quite comfortable moving files and folders? If not, please contact PG Music Support (see the Tab, above). We fellow users cannot take any responsibility for you losing files, although if you have your external USB drive from PG Music, you can always reinstall.

These instructions are for Windows. Mac would be a similar process by dragging folders but I can't help with that. If you are comfortable proceeding, make a folder on your 'other' internal drive (I'll call it Drive E for this example) and name that folder BB, so the location would be E:/BB

Then using a file manager utility (I use Total Commander but File Explorer will do) copy the C:/BB/RealTracks folder to E:/BB and copy C:/BB/Drums to E:/BB so those two folders appear under E:/BB

Copying the RealTracks folder especially may take a long time!

Go into BIAB and use the Options, Preferences, RealTracks and choose a Custom location. It would be E:/RealTracks.

Do the same process for Options, Preferences, Drums choosing E:/Drums

Test BIAB

Once you are sure everything works, you can consider deleting the two folders on your C drive, C:/BB/RealTracks and C:/BB/Drums
