Copying may delete some data-what?!

This isn’t a question about FontCreator exactly, but I have been using the program to clean up some fonts. I have put kerning and metrics in where there were none, changed some glyphs, and have been saving my fonts like normal. I went to copy them to a CD for backup, and I got a warning from Windows saying if I copy these (font) files, some data associated with them will be deleted. What data would that be? It seems silly, but I am afraid that if I copy the files then all my work will be lost or something. Does anyone know what that means, and is it safe to copy the files to different locations on my computer and/or network?

It sounds like Windows being silly again. Let me guess, you’re using Vista?

Try uninstalling the fonts first, then copy them and see if you get the same message.
