Problems Copying Virtual Machines to an External Drive?

If you are new to the world of virtualization (as I am), you may run across the same problem that I did today. While attempting to move a bunch of vm’s over to my external usb harddrive I was constantly getting errors about there not being enough space (despite having plenty of room):

Cannot copy FILENAME: There is not enough free disk space. Delete one or more files to free disk space, and then try again

Turns out the problem is with the external drive being formatted with Fat32. I guess you can’t copy files bigger than 2 gigs to a Fat32 drive. The good news is you can run the following command to convert a Fat32 to NTFS and alleviate this problem (though you may want to research the up and downsides of doing this). From a dos prompt run:

convert F: /fs:ntfs

This will convert the F drive to NTFS for you. Note: you cannot convert back to Fat32, so make sure you want to do it.
