What to do if you modify the extension to make the file unusable

1. Double-click to open "My Computer";

2, click "Tools-Folder Options";

3, switch to "view" label alum, tick "Hide known file type extension name" option;

4. Click "Apply-OK" to close the window;

5. Rename the file again, there will be no unusable hints.

Through the above settings and then windowsxp can directly modify the filename without the file extension resulting in the situation of the file is not available, I hope you have some help.
