You'll might also want to delete all that CYA electronic flotsam from last year. Don't do it. Back up the files first. You never know when you'll have to cover your own ass. Don't permanently store important files on floppies.
Floppy disks are notorious for losing important bits and corrupting files.
Use them only for backup copies. Round up missing Mac files. If you don't have a file icon but you can see the listing for the file's title, you probably need to rebuild your desktop. Hold down the Command and Option keys while rebooting your machine. This tells the Mac to go out and find everything again.
