I wanted to speak about the Disk Image thing because no one has yet. If I am wrong in my explanation someone please correct me as I am not an expert, just experienced. One thing that confuses many people, especially Win-Tell users, is that unlike DOS based systems, MACs deal with Volumes and not Drives. This allows there to be multiple Volumes on a single disc (I know DOS can too) and helps the operating system keep track of removable volumes (like CDs) better than the Win-Tell systems. As anyone who has seen the error “Can not read drive A: Abort, Retry, Fail?” knows, simply removing the disk doesn’t let the OS know anything. Having to unmount Volumes keeps everything under control of the OS, causing less errors, although it is frustrating for Win-Tell users who want there CD back and cant find the button.
This background is useful in understanding the Disk image files. There are several reasons for using them. It is a convenient compression format, doesn’t require 3rd party software, and you don’t end up with a ZIP and the folder it crates. Also, I have downloaded more than one file that was a compressed disk image rapped in a ZIP file. It ended up being 3-4 times the size of the ZIP package.
