Thanks for your answer! Usually, I download some files onto the ramdisk. I don't want to save the files on the hard disk after reading. So I want to know how to do it. Now I'd like to consult your opinion. Maybe I can press "ctrl+A" to select all the files in the ramdisk and then deleting them with pressing "shift+delete". I can also delete them with formatting the ramdisk.
Thank you for helping me correct the grammar mistakes at the same time!
