For various unpleasant reasons involving very large files and FAT32, I'd like to know if there is any way I can create a mountable disk image which is stored in multiple smaller (ie, "smaller than 4GB") files — for example, like OS X's sparse bundles.
Performance isn't a concern, so a solution involving, eg, FUSE or TrueCrypt would be completely acceptable.
(of course, I realize that one option would be to reformat the FAT32 disk… But that would create other problems, so I'd like to rule out this possibility before I think about them)
