Extracting PPT templates (.pot) from .ppt files

[ramian]

I've got this rather large bunch of blank powerpoint files which are supposed to be used as templates but are in the .ppt file format. I'm not able to access such ppt files from the Slide template dialog within PowerPoint. Only .pot files are visible. Is there a batch method of extracting the template files from all the powerpoint files (.ppt) and saving them as .pot files?

I know I can manually save them one by one, but with more than a 100 of them, I don't really have the time. So, I'm looking for a batch or automatic way of converting/extracting the template (.pot) files from them.

Thanks!
