Sep 21, 2007  How to Install Software from DMG Files on a Mac 21 September, 2007 by Tom Harrison in mac os x A.DMG file is a container file commonly used to distribute applications for Mac OS X. Installing software from one of these requires you to mount the image and move its contents to your computer’s “Applications” directory. Removing these files is as easy as the installation process: select the file and drag it to the Trash. There are cases where the software is more complex, such as Adobe’s suite of programs or Mac optimization software OnyX’s installer files. If this is the situation, just open the disk image. Aug 09, 2015 Within windows, the file can not be burned because there is no disc recognized. From my mac desktop, I can try to burn it, but it takes me to the windows 10 installation screen. I also still have the old windows 10 iso file under the parallels dropdown menu from the mac desktop. It can not be selected under the CD/DVD 1 option because it was. Jan 02, 2015  Assuming you’ve run the set up to install the programs they contained then yes, you can delete setup files safely. The programs will continue to work without them. However, the answer is also no: you don’t want to delete them.

Easier solution:
Move the DMG to /tmp/ before opening it. Then forget about it.
Files in /tmp/ get deleted on reboot.
If you decide you want to keep it, move it back to your Downloads directory or wherever you want it.

Great Idea!
So the cmd whould be:
mv '/Users/MyShortUsername/Path/To/MyDownloaded.dmg' '/private/tmp/'
Obviously, you must replace 'MyShortUserName' with your correct username , replace 'Path/To/' with the correct path to your dmg file and finally replace 'MyDownloaded.dmg' with the correct name of your dmg file.
If you don't use the quotes for the source path and the destination path, just remember to escape the spaces in the paths with backslash! (')

You know, you don't have to use /private/tmp. Just /tmp will do. In fact, it's preferred to use /tmp.

I go the other way. I keep ALL dmg files.
Every so often I move them to an 'Installers' folder, thus keeping the downloads folder clear. Less often I check the total size of the Installers folder and back up to CD/DVD and then clear it.

Or you could use a crontab:

With something like the following:

This will move any files in the ~/Downloads/ folder, to a child folder called 'archive' on a daily basis... then after 30 days, delete it.

Although, run at your own risk... its job is to actually delete data.

Can You Delete Dmg Files After Installation Software

Wait wait, let me get this straight… if I have files I don't want to keep, I can put them in the trash to get rid of them?
God bless Mac OS X Hints.

Dmg Files Delete

Good luck USING them after you put them in the trash. This hint was about continuing to use DMGs that are in the trash. You know you aren't going to want to use it, so always throw it in the trash, then continue using it.
Personally, I download to the Desktop so everything I download is extremely obvious to me. I also have it sorted by 'Last Modified' so DMG downloads appear in the upper right. Can't forget those!
