For local files, it's an amazing feature to be able to space-bar open a PDF document and quickly swipe through the contents of it.
How can I enable this for pdf files stored on a volume exposed by FileProvider?
Thanks David
Can FileProvider provide the full quicklook experience for PDF's?
If a file is downloaded within your File Provider extension, space-bar quicklook preview should already work on PDFs documents.
If a file however is not downloaded... then it becomes a bit tricky. You could have your own extension like .myextension for non-downloaded files and then implement your custom Quick Look Preview Extension where you could show ie PDF page images fetched from the server or something like that. But I'm not sure if that's what you're aiming at here.
