I can't copy EDITORCONFIG file to other directories

I already created a directory with .html and .css files.

Now I want to copy all the files in this directory from my USB key to another USB key, but I've a problem with the .editorconfig file (EDITORCONFIG). I can't copy it to another key, or to other directories on my computer.

So without this file my HTML page:

And here it is after copying:

The error code is 0x80070570

"Impossible to copy the file. Unexpected error. If the error persists, is possible to use the error code to search more informations on the problem.

Error 0x80070570: directory or file is damaged or unreadable."

How can I solve this problem?

Windows explains what the problem is in the error message:

Error 0x80070570: directory or file is damaged or unreadable.

It sounds like disk's file system is damaged. You should get it fixed ASAP, otherwise it may result in further damage and data loss.

Right-click the disk that hosts the problematic file and open Properties. On the Tools tab click Check in Error checking section. Then click Scan drive. Windows may complain that it's unable to unmount the drive because it's in use and that scheduling scan to next reboot is necessary, allow it to schedule it and reboot immediately. The scan may take a while (even few hours on HDDs with heavily damaged file systems), don't interrupt it.

You may also want to check your hard disk's SMART status, it's possible that this problem is an early symptom of incoming disk failure.
