:?: file:/mnt/sda2 - Permission, Modify content, Error:!:

Sorry -- right mouse click on the icon, select actions, go to change read write mode, left click.

Drag and drop, just like Windows (or Mac): you can "open" 2 views of the drive, find the file you want to transfer, right click on it and drag it where you want it. Otherwise, there's "move to" or cut and paste.
