Bulk Rename utility does not display the extension also renamed

In our traditional impression, to change the file extension, you need to first display the extension through the system settings, and then change the name. In fact, if you use some renaming software, you can ignore the file name extension is displayed, directly in the extension project to fill in the new extension, the implementation of the Rename command to implement the file name extension of the batch changes (Figure 5).

Small tips:

You can also go to the folder's command Prompt window and execute the COPY *.* *. JPG, which changes the file name extension once. Where "*.*" represents all existing files in the directory, "*. JPG "is changed to JPG format file.
