VMware Tools provides VMware HGFS File System to handle its Shared Folders feature.Ģ. How is VMware Fusion handling the sharing of Mac files in the HFS file system? Limitations of the FAT32 File System in Windows XPġ. The 32GB Limit you're thinking of is in reference to XP's ability to create and format a FAT32 partition however that doesn't stop XP from mounting and using FAT32 partitions larger then 32GB created by other methods. I have a couple of questions for those in the know: I thought Mac and PC could only share FAT-32 disks, which are limited to 32GB. The Mac folders are on a disk that is setup as a Mac hfs disk, it's larger than 32GB, and yet I'm able to share folders (read and write) with Windows XP in VMware Fusion. When I set up VMware with Windows XP as the guest OS, I was asked if I wanted to share folders with the Mac.
