Troubleshooting

Use these checks for common EMPF Preview, Windows Explorer and Seer plugin issues.

I still see generic icons

Try switching Explorer to Large icons or Extra large icons. Windows may still be using an older thumbnail cache.

Thumbnails work after copying files, but not in the original folder

Windows may have cached the generic icon for the original file. Copying creates a new file identity, so Explorer requests a fresh thumbnail.

OneDrive Desktop files do not show thumbnails

OneDrive Files On-Demand can interfere with Explorer thumbnail generation. Try copying the file to a normal local folder.

Seer preview does not appear or update

First confirm that the EMPF Preview plugin has been added in Seer. If setup is correct but the preview is stale, Seer may be caching generated HTML previews. Clear the Seer cache or test with a renamed copy.
