Many times when we download files, we are not sure about the size of the file. Only when the download starts, we come to know the file size. Get File Size is a free Internet Explorer add-on that allows you to find out the size of a file before downloading it.
Once the add-on is installed, it will add an item to the right click menu. All you need is to right click on the download link and select Get File Size.

Get File Size will show you the date when the file was last modified, file type, server response time and estimated download time. Get File Size can also retrieve the dimensions of JPG, GIF, PNG and BMP images without downloading the whole image.
