The shared folder with the emulated driver is in FAT, which prevents windows from opening large files

It is not possible to open big files in the emulator e.g I wanted to use it to unarchive an XDI file which uses the Proprietary WinArchiver format, to get the ISO file back on my mac. But Windows cannot copy the file to its system or even open it in a third-party program because it is bigger than FAT allows.

The shared drive could appear as ExFAT for windows, to allow extra flexibility in these cases.
