It may look like a file, but that's just some trickery in the Finder--if you right-click it and do 'Show Package Contents' (or look at the directory in Terminal), you'll see what I mean. (That being said, it's presented as such to prevent the average user from poking around inside the 'file.' It's meant to be modified by iPhoto itsef only.). Click to expand.Besides Time Machine (which requires directory hard-linking, a Leopard addition to HFS+), I'm not aware of any (though if you're using it for Mac backups at all, even manual ones, I'd say HFS+ is still a good idea since you're less likely to run into problems with the type or number/length of characters in file names or file sizes since different file systems have different restrictions here). If file/folder permissions are an issue, HFS+ is really the only file system supported on OS X that contains this feature. FAT variants simply don't support this at all, and NTFS does, but Apple's implementation is read-only.
