If you downloaded or copied files onto the D drive, you can either move them over to C, or delete them to free up space - just be careful which files you delete.

If you already know what the DMG and PKG files are, you can skip to the second paragraph. For those who are learning about this type of file, we will describe its purpose below.
What is a DMG file
If you want to install a third-party application from the internet, you need to download its installer file with a .dmg or a .pkg extension. Both types of files, DMG (Apple Disk Image) and PKG (package installer), are only used on macOS. In most cases, once you download and open a DMG or a PKG file, you are asked to transfer its app to the Applications folder. Then you can launch the program and happily use it.
Since .app files of programs are located in the Applications folder, you can delete DMG files and package installers. Besides that, developers regularly update apps, so if you want to use an updated version of particular software, you will need to download a new installer. Since there is no need to keep useless installers on your Mac, you can remove them using Cleaner-App.

How To Delete Dmg Files On Mac
Lots of good points in this thread. I've re-thought how this should work.
Can I Safely Delete Dmg Files
My problem is that my downloads folder gets cluttered with dmg files. I can't remember which ones I've already installed. Some of them I have opened and installed, but I've forgotten to move them out of my downloads folder. Some of them I downloaded but haven't opened yet.
My new version of the script moves the dmg file when it is mounted. To use it, save this script to '/Library/Scripts/Folder Action Scripts/' and attach this folder action script to the /Volumes directory. Ideally, my script would trigger when you eject the disk image, but by then it's too late; the disk image is gone, and there's nothing left for AppleScript to process. I figure triggering on mount was pretty good, since I really wanted to know what dmg files I had opened or not.
Can I Delete Dmg Files After Install
Most of you didn't want to delete the dmg file. That's a good idea. My script now moves it to a dmg_archive folder. Feel free to change this to suit your needs.
