I copied contents of my pendrive to a directory in mint machine. When I tried to click the copied contents through gui to view it said, "You do not have the permissions necessary to view the contents". In the other thread it was said that I can view my file by elevating privileges to the gui by gksudo command but do I have to do that everytime i copy a file from an external source. What can be done?. I need to differently copy or add permissions to the directory?. Please let me know.
