What version of Windows are you running? You may be able to transfer them if you use media formatted in exFAT if your windows computer is on windows 7.

 

I did not search that, I searched google because I remember seeing it once here before. I never knew, until I saw that thread, that you could split DMG files. To me, a DMG was like an EXE but I was clearly wrong.

 

It's an inherent limitation to FAT32, not a Mac vs FAT32. FAT32 doesn't support file sizes over 4 GB.

 

You wouldn't be able to reassemble your split files on the FAT32 HD, because, as mentioned above, the FAT32 filesystem does not support files larger than 4GB.

But, uhh, you could use the split command line utility...
