If you try that on a large external drive you can go over the fat32 limit. Zipping the library and transferring the large zip file and then unzipping seems to take less time overall.

I doubt the library metadata file will hit the fat32 file size limit.įor large libraries the transfer times become very long because there are so many files. The iPhoto library can grow larger than 4GB since it's really just a folder with a bunch of pictures in it.

My iPhoto library is currently 315 GB and I have it on a Journaled 4TB drive. If it is a Fat32 limitation, can your iPhoto library grow to more than 4GB? Will it recognise it as a folder with multiple files, or treat it as a single file? Is it Fat32 that has a limit on the maximum file size? You cannot copy files > 4 GB on it right? I can't seem to remember if that was a Fat32 limitation or an NTFS limitation.
