need help with a file extension

we have a file/program with a .dmg extension
our understanding is that it is a Macintosh program
OS X Disk Image File
We do not know what a disk image file is
could somebody please explain it to us and how do we go about opening up the file
do we need a specific software program to open it up ??
is it a valid file/program when it has a .dmg extension ?
your help with this matter is greatly appreciated

Thanks, Joan

I presume you're using a Mac? In that case drag and drop the .dmg file onto Disk Copy, a utility inside the Applications/Utilities directory. That should mount the file. Then copy the contents of the disk image to your hard drive, and you should be all set!

If you're not using a Mac, I guess you won't be able to do anything with it.

WHen a .dmg file shows up on the OS X desktop, it acts like a new drive with its' own directories and files.
