If what you want is all the files on the same group, you may use mount options to set that. For example: mount -o group=mygroup /dev/sdx1 /mnt/myusb But if you want commands to change groups or permissions, you should reformat the filesystem. If you need Windows interoperability, you might want to try NTFS, I don't know if it works, but if you have the device, the machines and the time for it, you might as well test it. HTH, Filipe
