How to clear download clutter
It drives me nuts when I download a program, or upgrade an old one, and
it arrives with assorted junk. What am I supposed to do with the DMG
file that opens the program ? Junk it, or save it for future use ?
Answer : Disk images ( DMG files ) act like a virtual version
of a hard disk or flash drive, which is why they pop up like portable
drive icons on the Mac's desktop when you open them.
The file or program you downloaded is stored on this virtual disk.
To install the file on your Mac, you usually just have to
double-click the installer files or drag the files to your Mac's hard
The DMG file is basically just the container for the program or file
you were downloading to the Mac.
Tossing it in the Trash after you've installed the software is fine.
But for backup purposes, you may want ot make a copy of the file that
was on the disk image.
You could, for example, round up all the files contained on those
downloaded disk images and burn them all to a CD for safekeeping before
you trash the files.
