Not to be critical but please check spelling and grammar. I had some trouble understanding your last post.
Inside of Windows there are garbage collection routines. Not certain where to go, but you can tell Windows to delete temp and cache files. That may help.
How was the drive formatted NTFS, FAT32, etc? There are drive size limits depending on the format.
The reason I asked for you to check the C drive properties and Finder Get info, is to see if the Mac filesystem and the Windows filesystem think the virtual drive size is different.
