Well, that is just too weird! I always DO select "Overwrite" in FZ, so I can't imagine why the file sizes are different. All four of the "pages" are different sizes. Does FZ compress files??? There's no question in my now fading mind that the files on the left are the same ones that are dragged over to the right. What on earth is changing them? I'm beginning to think the fault lies with the server. The guy who offers us space said something about his either having changed servers or his server changing something. I didn't pay close attention, 'cause I didn't think it would matter. Plus, I also just made a few updates on another site I do (different server/host) and it went through my usual process easily, no hassles, so it's not Xara or FZ. Gonna crash and take this up in the morning. Thank you!
