I'm trying to shrink my C: volume to allow for dual booting, but the built in utility is getting hung up on $BITMAP. It was originally having problems with another unmovable file $DATA, but after using contig that one was moved out of the way.

However, no matter what combination of contig options, safe mode, whatever I try, $BITMAP won't move. 200GB free, and I can only shrink the volume by 9GB because of it. :)

I'd prefer not to have to perform a complete reinstall.

Or it seems, I have to go about disabling bitlocker in order to allow a 3rd party tool to work on the partition... Last time I was messing with partitions was from before Secureoot and Bitlocker days. :)
