I have a rather large folder containing many PDF files. Opening each and every file from Explorer seems too tedious.


  • Lightweight PDF viewer
    There is no need to offer advanced options.

  • The ability to navigate in the current folder in alphabetical order by a keyboard shortcut.

  • Works on Windows 8.1

  • Bonus: Rescale each PDF to fit the viewer's window size.

For example, IrfanView and Windows Photo Viewer do have this feature.

I have already tried opening Foxit Reader with multiple PDF documents as tabs. Navigating would then work by hitting Ctrl+W to close the current tab and thereby switching to the next tab. However, it seems that Foxit Reader doesn't preserve the alphabetical order in some cases.

  • @NicolasRaoul it will. I understand the intention and motivation, but in this case, I feel like it's nitpicking

  • +1 Thanks now that's a great answer! :-) The problem if we are not strict is that answerers will just post links without saying what requirements the product fits or does not fit, leaving it to every one of the 1300 visitors to figure out by clicking the link of each answer.

  • Nice, I was looking for such a PDF Viewer, but I already had Sumatra installed, just didn't know about that shortcut.

  • It might be worth adding the command to make SummartraPDF into your pdf previewer for explorer & outlook, etc: forum.sumatrapdfreader.org/t/outlook-preview/700/7 discusses. Commented Jan 12, 2021 at 5:37
