GetFileSize is an Internet Explorer add-on that allows you to find out the size of a file before downloading it. Just right-click on the link to a file and select "Get File Size" from the menu; the program will immediately show you the size of the file in a small pop-up dialog. In addition, the program shows you the date when the file was modified, and converts the size in bytes, kb, and Mb. Works with any kind of file link, including images, programs, videos, and so on. Simple, but very handy.
