What's an "exe file?" What's an "exe" file and how does it work? "Exe" is short for "executable" and means the file will do something when you click on it's icon. You know, the little pictures that sit on your desktop. And the word "execute" means to start up. Basically, my "exe" files are web pages that have been compressed and zipped in a program to make the file size smaller for downloading, and you will not need an unzipping program installed on your computer to open it. It's been programmed to open automatically and "execute" when you click on its icon. Executable files are very common, and very scary to some people.  They think the file will contain a virus and it could. Viruses are most commonly shared by email.  The executable programs I'm offering on eBay are all virus free.  They've been scanned using updated McAfee Virus Scan software so you can be assured they are safe to download. If you're doubtful or unsure, save the download to a floppy disk, then, use your own virus software to scan it again before opening the file.
