This tutorial will show you step by step what to do when thumbnails for images and videos are not showing in File Explorer in Windows 10.
But first:
When you open a folder with photos or video files in Microsoft Windows 10 File Explorer, you will normally see thumbnails (reduced-size versions of photos or videos).
Thumbnails will appear for almost all common 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.

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