2. Do I Need To Keep Dmg Files After Installation Download

1. On a game it usually functions as cd, so I keep those files. But after installing a program like Google Earth and putting the needed file in Applications, do I need to keep the. Once the applications are installed, they do not require the dmg to run.
2. Sep 16, 2018  After completely finishing installing windows 7 home premium via an.iso image, is it ok to delete the iso file afterwards? If I delete ISO what will happen? Discussion in 'Installation and Configuration' started. Presence or absence of the.iso file doesn't matter to an existing Windows installation. An.iso file is simply an image.

4. Dec 27, 2006  Well, after installation I tend to keep the.dmg file in the same folder where the application was installed. Then if the application is ever corrupted I can just delete it, and do a reinstallation from the.dmg without having to go back and download it again.

One of the most common mistakes I see among new Mac users is fumbling with how to install new software. The process for installing new applications on your Mac can be confusing at first because it differs greatly from Windows’ software installation process. Nevertheless, the Mac method of installing software is actually quite simple and intuitive once you are accustomed to it. If your desktop is littered with DMG files and white “drive”-looking icons, read on!

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. Nov 07, 2011  Managing and installing applications distributed with DMG files Periodically people who download applications end up with collections of DMG files that they are. Even though TransMac can open and extract files from a dmg image, only certain data files (image, video, text, html, sound, etc.) will be usable on a PC.Windows is not be able to install or run Mac software.

What are .DMG Files?

DMG stands for Disk Image, and is a format commonly used to distribute files and applications among Apple computers. A DMG file is like a virtual DVD or hard drive. They can be “mounted” on your Mac in order to work with their contents, or even burned to an actual physical disc.

In order to understand the concept of a DMG disk image, think of a storage volume such as a CD, DVD, hard drive, or external drive. A DMG file is like one of these devices in that it serves as a means to encapsulate documents, images, software, and other files. The difference is that with a DMG, there is no physical storage medium. There is only the DMG file, which can be written to a hard drive, burned to a CD or DVD, or sent over the Internet.

In order to work with the contents of a DMG file, you must mount the the disk image to your system. This may sound daunting, however “mounting” a DMG file with Mac OS X is no more complicated than double-clicking it’ icon. The operating system will load the load image and place a new icon both on your desktop, and in the sidebar of the Finder. The icon will have the same name as the DMG, and you’ll be able to browse through its contents like any other folder.

Once you are done working with the contents of the file, you will want to remove or “unmount” it from your system. Do this by opening the Finder and clicking the eject icon next to the virtual drive’s icon. Or, go to the Desktop, click once on the icon, and press CMD+E.

Software installation with Mac OS X is very different than in the Windows world. On a Windows PC you run an installer, tick off a few checkboxes, and wait for the progress meter to reach completion. There usually is no such “installation wizard” on a Mac &emdash; you simply drag and drop the program into your computer’s “Applications” directory. The trick is that most Mac applications are distributed as images called DMG files, and many new Mac users end up running applications directly from the image instead of installing them to the “Applications” directory.

Enough explanation, here’s how to install an OS X app from a DMG file:

1. Find the downloaded file, which usually ends up in your Desktop or Downloads folder.
2. Double-click the .DMG file to mount it. A new Finder window showing its contents should appear.
   • If the window also contains a shortcut icon to “Applications”, drag and drop the app onto the shortcut.
   • If not, double-click the mounted volume on your desktop and drag the app icon from there to the “Applications” icon in the Finder sidebar.

Further Explanation

Alright, that was the abridged version. Here’s the long version. I’ve just downloaded the DeskLickr application, and the DeskLickr_1.2.dmg is sitting on my desktop. I double-click it and a new icon labeled “DeskLickr 1.2” appears on my desktop. Here’s what my desktop looks like at this point:

Since most of the time a new Finder window also pops up when the image is ready for use, this one is now sitting on my desktop:

Different applications are going to show you slightly different Finder windows. Each application’s designers like to add their own artwork. Glitter aside, most applications are trying to tell you the same thing. See the arrow pointing from the DeskLickr icon to the “Applications’ shortcut? It’s telling you to drag and drop the icon into that folder. Once you’ve done so, the app will be installed.

If a program doesn’t provide a shortcut to the Applications folder, you’ll need to pop open a new Finder window. Press CMD+N to open a new window, then drag the program over to “Applications” in the left-hand side of the window.

Once the new program is installed it’s time to do some house cleaning. You no longer need the disk image you downloaded, so follow these steps:

1. Close any Finder windows that have been left open.
2. Eject the disk image (not the .DMG file). Click on its desktop icon, then press CMD+E.
3. Delete the .DMG file by dragging it to the trash.

That’s it! Your new Mac application is ready to use. But wait…

Bonus Tip: Add Your New Application to the Dock

I knew you were going to ask, so I figured I would cut you off at the pass. In order to add the new application to the dock, follow these steps:

1. Open up a new Finder window.
2. Click on “Applications”.
3. Locate your new program’s icon.
4. Drag the icon to your Dock, and drop it wherever you like.

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.

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.

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!
