Copy Folder Thumbnails To a File

I have a movie archive. Each film and its poster image are in a different folder. So there are a lot of folders. Each folder has its image in it as thumbnail.

Anyway, here is my problem:

I want to copy all folder thumbnails, folder names and folder sizes to a file, for instance word, excel, image files…

I know that it can performed with printscreen key, and paste a file. But, the folder window can not show all folders in a screen. Think that there are 1000 movie folders. We can see only first 30 folders of them in a screen.

I need to print-screen all of them in one time, and paste it to a file.
Or, get thumbnails, folder names and sizes as a list with a program.

What do you offer me about it?

Thanks in advance.

Regards…
