I scanned my hard drive with a disk space analyzing program and I noticed that I have hidden Recycle Bin folders on the "D" and "E" drives which are not empty. One is 4gb, the other 6gb. I can't empty these folders. If I empty the Recycle Bin from the desktop icon, it empties only the Recycle Bin folder on the "C" drive.
My question is how to delete the content of the Recycle Bin folders on the "D" and "E" drives, and is it safe to delete it?
