If your system has a floppy drive you can use another computer to place the needed driver on a floppy disk an then reinstall them.You could use a USB drive to transfer the drivers to the computer if no floppy drive is present.There are also several ways to connect a second computer to the faulty system so the needed drivers can be transferred and installed.

Another factor is that external USB floppy drives are a seldom-used item, whereas an internal floppy drive could be leftover stock from when they were a common commodity in every computer.

From which platform? From a Windows platform, insert the floppy into your disk drive. You can do this any number of ways but I'll give you the two easiest for me: 1. Right click on start, hit explore, drag your data to the disk drive. It will copy it, not move it. Remove disk. 2. In the program that opens the data you want to transfer (so perhaps Word for a paper you wrote), have the data open in the window, click on File, Save As, and Save it to your floppy drive (usually drive A). Close program. Remove disk.
