This question relates to Ubuntu 12.04 LTS. I wish to move a folder from the desktop into the applications folder at home/usr/share/applications. When I attempt to drag the folder from the desktop to the applications folder, I get the following message:

"Error moving file: Permission denied"

Permission or no permission, I want to move a folder from the desktop to the above said applications folder. How do I authenticate so I can make this move? There is no opportunity to authenticate when I get the error message, only "Skip" or "Cancel". I don't want to skip or cancel, I want to authenticate and move the folder. How do I do this?

Thank you!
