Fix: Thumbnails not showing in Windows 10 or 11 File Explorer

Thumbnails for images and videos not showing in Windows 10 or 11 File Explorer? Here are a few solutions you can try to fix the problem.

When you open a folder with photos or video files in Windows 10 or 11 File Explorer, you will usually see thumbnails (reduced-size versions of images or videos).

Thumbnails will appear for almost all video formats (e.g., MP4, AVI, MKV, WMV, FLV, MPG, and MOV) and image formats (e.g., JPG (JPEG), PNG, GIF, and PNG).

But, if you only see default icons (e.g., VLC icons) and no thumbnail previews, then you can try the solutions on this page to fix the problem.

Make sure there's enough space on your system drive

The following solution is from a comment on another website.

When your system drive (the drive where Windows 10 or 11 is installed) becomes full, Windows will stop generating thumbnails.

Check the disk space of your system drive (usually the (C:) drive) and when it's almost full, then delete or move things from your system drive.

When it reaches a minimum of 1 GB remaining disk space, the thumbnails probably show up again.
