G'day, this might seem like a trivial question but it has been confusing the hell out of me for the past month. I am a recent convert from a PC to a new iMac 24", and I am learning my way around things. One thing I dont properly understand is how to download programs and where to store them. e.g. I downloaded google maps and VLC. The files went into the download icon next to the trash bin. When google earth finished (dmg file) I double clicked on the icon and it came up on my desktop beneath the time machine icon. Clicked on it again and it launched google earth. I then ejected it and removed it from my download "tray"... now it is gone. ****.... Did the same thing with VLC player except that instead of ejecting it I dragged it to the applications folder. Saw the little witches hat and dragged that down to my icons along bottom of screen. But I still have the dmg file in the application s folder, will that always stay there??? If someone can teach me the proper way to download and install files and programs it would be appreciated.
