Use the ROBOCOPY command in Command Prompt.
Here's an example to copy all GIF and JPG files from one folder (including subfolders - that's what the /S is about) to another:
ROBOCOPY C:\Users\USER1\ImagesVids C:\IMAGES *.gif *.jpg /S
and, to do the same for specific video file types:
ROBOCOPY C:\Users\USER1\ImagesVids C:\VIDS *.mov *.mpg /S
When I did my testing I had already created the C:\IMAGES and C:\VIDS folders before executing the ROBOCOPY command. Of course, one substitutes the correct source directory, which is the first argument to the command, and destination directory, which is the second. The third through nth will be the *.extension list of all the extensions you wish to snag, and the final argument is the /S that says to include all subfolders as part of this process as well.
