thanks, Ingo. So I blame Microsoft :-)
the cur and new directories are indeed empty.

what would happen if I use tar/gz to zip the mail folder and then move it to FAT 32.
when I copy it back to ext3 before unzipping it, the files should still be ok. Right?
that would be useful if I want to carry my mails on a USB stick which is FAT 32 formatted.
