Hi, Im still starting with SUSE.
May somebody help me copy files again to external devices? (USB memkeys, floppy) ?

What happened?
I was playing with different scripts, below are the chronology of events:

1) Made Nautilus as a root
su -
password: ****
Result: Able to copy files to USB memkeys

2) Tried another script
xhost + localhost
localhost being added to access control list
sudo nautilus --display=0:0
Result: (nautilus:4550): Gtk-WARNING **:cannot open display: 0:0

3) Tried copying files again to USB memkey as a root user, the following error message appeared.
[Error "Invalid parameters" while copying"/home/Architec...nux-6ovf:~.png"]

I dont know if I had messed up something within it. Please help me..
Thanks in advance
