This is caused due to the fact you most probable opened a file handle but you never closed the file handle. You can:

Close the handle

Restarting the computer usually fixes everything.

thank you i will try this
will re-reply if it didnt work

Moved to Ask a Pro.

If it says Access Denied when you do rd * it is because it tries to delete everything on the HDD including the rom directory. So it will say Access Denied. If you try to delete a specific file ex. rm test then you will probably have to either close the file handle or restart the computer. But, When you restart the computer beware that files may not be saved if they have not been flushed!

I tried:

local file = fs.open("/password.txt");
file.close();

and worked.
