So I recently got an MBP and I'd like to share an external HDD between it and a few of my Windows machines. I just bought a 500GB hard drive which I'm gonna put in an external enclosure. Would it be possible to format one 15GB or so partition in FAT32 to use as a "swap" file to transfer large files between the two different OSes?

In other words, my question is basically: can Mac OS X and Windows XP both read/write a partition formatted in FAT32? and if so, what is the max size of both the partition and files in FAT32?

thanks for your help guys!

Windows XP can only make maximum 32-GB FAT32 partitions.

(side note: On PCs, I get around this by reformatting first using a Windows 98 boot disk, then installing 98 then XP.)

As for the max file size, according to Wikipedia, it's 4 GB.
