Glary Soft has identified about 27.91GB of duplicate files in my laptop with new BIAB install. A number of them seem to be "Direct Input" versions of the same files.

For example: C:\bb\RealTracks\Direct Input\Guitar, Electric, Rhythm PopMotionHeldHiGrit ev 100 Direct Input alongside C:\bb\RealTracks\Guitar, Electric, Rhythm PopMotionHeldHiGrit ev 100

Are these duplicate files necessary? I'm trying to figure out why my brand new laptop is so full. 19.4GB free of 475GB.
