Hi folks, We'll work on adding a way to disable this dialog for good. In the meantime, it can be disabled with a command line option. You'll have to start Drive manually for this to work.
On Windows: Start -> type "cmd.exe" and hit Enter In the command window, enter this exactly:
"C:\Program Files (x86)\Google\Drive\googledrivesync.exe" --noshow_confirmation_dialog_on_delete
On Mac: Run the Terminal app (in /Applications/Utilitites) In the terminal window, enter this exactly:
/Applications/Google\ Drive.app/Contents/MacOS/Google\ Drive --noshow_confirmation_dialog_on_delete
