Save to a removable medium
This button allows you to save the
document to a removable medium : cd rom, usb key
etc...
When you push this button, you are asked
to give the path of the medium e.g. /mnt/removable or
/Users/Volumes/usb_key
depending on your medium and your O.S.. This path is kept so the next
time it will not be necessary to type it again.
Nevertheless if you want to change it you use the menu command File/Saving path and you type the path you want.
