What file systems can Snow Leopard read? I just got a MacBook Pro for my parents, and I need to get their files from a Linux desktop machine that most likely has either reiserfs or ext3 file systems.

I would like to know if Snow Leopard can read these files if I put the HDD in an external HDD case??

Thanks
It might be easier to connect the machines on a network and use rsync, nfs or ftp   to copy data, no extra software would be needed.

If you want to do this you will need MacFuse which allows OS X to read other file systems. A tutorial for ext3 is on this blog.
