Update Acrobat Reader and Rebuild Metadata
Installing the latest software update forces Adobe Acrobat Reader to refresh its cache and properly reload missing cover images for your recent PDFs.
Software glitches or disrupted connections to external drives can corrupt the thumbnail cache in Acrobat Reader. Updating the application resolves these underlying bugs and forces the recent-file list to rebuild its metadata.
Open Adobe Acrobat Reader DC, navigate to the 'Help' menu at the top, and click 'Check for Updates' to download and install the latest version.
Close Acrobat Reader entirely and reopen it. Wait a few moments to allow the Recent files list to completely reload.
Manually open a few of the PDF files that are missing their cover thumbnails to trigger a refresh.
Close and reopen the application once more. If prompted to reload the files that had been open, click to confirm. This action forces the application to rebuild the recent-file metadata, restoring the thumbnails.

Frequently Asked Questions
Why do PDF thumbnails disappear in Acrobat Reader?
Thumbnails often disappear due to corrupted application cache, metadata loading errors, or when the PDFs are stored on an external drive that was temporarily disconnected or experienced an I/O error.
Will reinstalling Acrobat Reader bring back my recent files list?
Reinstalling the application might fix the bug preventing thumbnails from rendering, but it typically clears your existing recent-files history. Updating the app through the Help menu instead usually preserves your history while fixing the bug.
How do I toggle between list and thumbnail view in Acrobat Recent files?
In the Recent files view, you can switch between a detailed list layout and a larger thumbnail layout by clicking the view icons located near the top right corner of the document list panel.
