Presently, all documents (txt, docx, pdf, . ), raster images (jpg, tiff, png, . ) and vector images (ai, cdr, . ) and many more are displayed in File Explorer's preview pane. This causes slowdowns, if a large docx or pdf file is read automatically for preview at folder opening. Can I selectively set which file extensions to preview (e.g. images only)?

Its only one button in the toolbar. If you set the icons to large thumbnails in the views menu, you can preview images, but documents etc that still need the preview pane are not previewed.

I am not adept enough to provide a solution, but I'm pretty sure the answer below stating this cannot be changed is inaccurate.
