FreeBSD and OpenBSD, AIX and Solaris claim some level of support for it as well. Unless you're using FAT32 or a network CIFS, it appears to be the best supported filesystem to me, given that you are using the proper version of UDF. I'm guessing a Windows partition layout would be most compatible as well on a magnetic disk. Also note that UDF claims to be able to write and rewrite files directly to RW optical media. I've never used it much in practice though. Andy
