So basically our customer uses our Nextcloud service and wants to use the preview function of the Windows Explorer and Adobe reader to quickly find PDF-Files without the need to open them.
Unfortunately exactly this is not working in the Eplorer folder from Nextcloud. If you take any PDF-File in there and paste it to the local computer, it will show as intended. Even if you paste it to a net-share.
I am not sure if this is a problem caused by Nextcloud settings or by the Windows PC itself.
Sorry to hear you’re facing problems

The issue you are facing:
PDF-Files cannot be seen via PDF-Preview Handler in Windows Explorer. Files are shown as PDF-Images instead of showing the first page of the PDF-File.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
Installing Nextcloud on the client and setting up a sync to the webserver
Setting Adobe Reader DC to the main PDF-Program and also enabling PDF-Preview in Explorer in the Adobe Reader Settings.
Enabling Always show icons, never thumbnails in Explorer options. Now every PDF-File should be showing its first page instead of the PDF-Icon.
It works everywhere but in the Nextcloud folder.
