How to solve the problem that the file in the floppy disk can't open

If you have a lot of important files on your floppy disk, what do you do if you can't open it when you need it? Here are a few ways to solve this problem:

1. is to the floppy disk from the inside out, and then with the index finger in the center of the floppy disk out of concentric circle, this can remove dust, but also adjust the placement of the floppy disk is not correct, and then put in the floppy drive to try.

2. Just try replacing another floppy disk in the floppy drive to see if it's a floppy disk problem.

3. If none of this solves the problem, it will be repaired at a professional repair point or the film is completely scrapped.
