The video of the square dance that cost money wants to be exported, and nothing is displayed in the computer USB flash drive. What happened? Is it write-protected?

First, make sure you have this video on your USB flash drive. Then you can display the hidden file by following the following steps:

1, open "My Computer" (note: it is called "Computer" in win7).

2. There is an organization in the upper right corner.

3, click on the folder and search options.

4. Find and review the advanced settings below, select Show hidden files, folders and drives, and then click OK. Then go to the USB flash drive to see if the video is displayed.
