Open from a removable medium
This button allows you to open a
document from 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.
