I was using my laptop regularly then suddenly after i start it the whole file names are missing.
The task managers name lists are the only names exist. What should probably i do, thx very much for the help.

First thing we need your complete computer specs filled out. Look at my specs it will give you a idea of the information that can be added.
For now what security programs do you have installed?
Have you run any security scans?
Have you tried a restore point to before this happened?
A restore point might not help because if you have a infection the restore point can also be infected.

As you can tell we need more information so we can give proper guidance.
