What is the difference between JPEG and JPG images? The file association feature of Windows seems to make a distinction, but the internet sources I've searched sometimes make a distinction, sometimes not. I've not been able to find an explanation. While I have your attention, how can a file have a four character extension, i.e. JPEG? I thought Bill Gates and God said only three were allowed, i.e. JPG. Thanks

3 letters is still used in DOS where there is a alphanumeric limit of 8 characters - starting w/ Win 9.x 256 characters are allowed and usually a suffix either 3 or 4 characters (.xxx) or (.xxxx) can be used - you can make your own file extension w/ any suffix you want (filename.wolf)

the difference is that E stands for EXTENDED picture graphic .. it is more something more than jpg ... for us it means nothing but jpeg files carry more information than jpg files.

It's just as some one mentioned above, some programs can only read one file format, either ".jpeg" or ".jpg". As to why 3 charecters for one and 4 for the other, I need a clear answer too. Thanks!
