I replaced my HD by basically doing a disk image. Almost everything worked flawlessly and I've been up and running for a couple of months. But for some reason I lost a lot of icons. For example, all my PDF files have that generic non-associated file icon. They open properly with Acrobat Reader, but there seems to be no way to change to what they should be.
I also have many htm files which are missing icons. Some are correct, some have that same non-associated icon. I am able to change individual icons on these files (not sure why properties give me this option here an not on the PDF files), but it only lets me do individual files, and not all of them at once.
Many other icons are improper too, including some of my off programs that just have a generic "exe" windows icon.
Any ideas how I can repair all these icons?
