I noticed on one of my web sales pages that I had left off the phrase "Supported Platforms: Win98/ME/XP/Vista/Win7," so I downloaded the page, added the phrase and re-saved it as a slightly different name.
As I was getting ready to re-upload it, I noticed that the file size had changed from 762 KB to 1498 KB!
I decided to re-open the original file, not touch it at all, and then save it under a different name. The size of the file AGAIN jumped to 1498 KB!
I took a look at the original file and the saved-without-touching-it- again file and the coding appears to be the same in both.
So what's going on here?
