your setup may sometimes fail to preview PDF files in connection folders.
Instead of showing the file preview, your machine displays an index file directory.
Lets explore what could be causing this annoying issue and how you’re free to fix it.
Launch Adobe Acrobat, tap on theHelpmenu, and selectCheck for updates.
Hit theDownloadbutton to drop in the available updates.
Restart the program and see if you’re free to preview PDF files.
Check the Filename
see if the file path or filename contains the number sign (#).
Sometimes, the Microsoft PDF Previewer might simply ignore the path that comes after the number sign.
The quickest solution to solve the problem is to remove the number sign from the filename.
However, that may not always be possible.
If you dont have permission to edit the filename, contact your IT admin for further help.
To check what preview handlers are available on your machine, go toHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PreviewHandlers.
Then, look to see if the filename contains the number sign and remove it.
If the issue persists, tweak your Registry parameters and enable a different PDF previewer.
