@michaelgilkes That makes sense. I was looking in my template folder and pretty much everywhere else than in the easyfolderlistingpro folder.
I changed “octet-stream” to “force-download”. In the plugin I’ve set “Link To Files” to [Yes], “Link Target” to [_blank] and “Download Target” to [Link (overrides…)].
Here’s the link to the site with your plugin: http://scan-in.dk/index.php/en/industrial-dosing/downloads
When using “right-click -> Save as…” the PDF download works fine. But when left-clicking it still results in a corrupt downloaded file.
