The issue of thumbnails not showing in your OneDrive folder could be related to a few different factors. Here are some potential reasons and solutions:
- File Thumbnails and Previews: If you're syncing files from SharePoint on-premises, thumbnails may not appear in File Explorer for those files. If you have enabled Files On-Demand, online-only files won't display thumbnails until they are downloaded.
- Windows Search Index: Sometimes, the Windows Search index may have an incorrect cached status, which can affect how files are displayed in File Explorer. You can try disabling the Windows Search service temporarily to see if that resolves the issue:
- Open the Services application by searching for "Services" in the Start menu.
- Find "Windows Search," double-click it, set the Startup type to "Disabled," and stop the service.
- Hidden or Temporary Files: Check if there are hidden or temporary files in your OneDrive folder that might be affecting the thumbnail display. You can show hidden files in File Explorer and remove any unnecessary ones.
- File Explorer Settings: Ensure that your File Explorer settings are configured to show thumbnails instead of icons. You can check this by going to the View menu in File Explorer and selecting "Options," then ensuring that the option to always show icons, never thumbnails is unchecked.
If these steps do not resolve the issue, it may be worth checking for updates to your OneDrive app or Windows operating system, as updates can sometimes fix bugs related to file display.
