Thanks soo much everyone for all the help.
I've installed reset permissions, reset LaunchServices using OnyX, rebooted, and files are still "unix executable" to start with. I then used FileUtils app to "Clear Executible Status," which makes them open in txt editor, and say they are 0kb in size. I then renamed the extentions, playing around with a bunch of different types, and no luck at all with any of them.
Here is a screen shot (

PS - here's something weird... I had a friend w/ Tiger send me a font suitcase which he zipped, and it did same thing, but then he zipped it twice (wierd, I know) and it worked! I unzipped the first one, then unzipped the second file within that first one, and WALLA, the suitcase actually looked and acted like a font. This doesn't help at all with all the other saved files, but it certainly helps. I might open a pc & try to double zip all the old ones & see if that does the trick.
