I'm trying to increase the size of the BootCamp disk on my imac. I had 32 Go (in FAT32) before. I deleted the partition. Now I try to use something bigger (80 or 90 Gb) but Boot Camp tells me that "the disk cannnot be partitionned besause it's impossible to move some of its files". Strange, I have enough free space (200Gb). Thanks for your advices...
