🎬 New in 0.4.6: Video thumbnails

Explorer now shows a representative frame for video files — Matroska .mkv, .webm, .mp4, .mov, .avi, and more — using Windows' own Media Foundation codecs. So it bundles zero extra bytes and streams the file (a multi-GB movie never loads into memory).

Also new

  • Settings import / export — back up your whole configuration, or move it to another PC, as a human-readable JSON file (Settings -> Diagnostics).
  • Check for updates — a button that asks GitHub whether a newer release is out.
  • Rebuild thumbnail cache — clears Windows' stale thumbnail cache so a format/size change shows up immediately.
  • More reliable camera-RAW thumbnails on a clean Windows install.
  • The About box now credits the original author (Nikolay Raspopov) and shows the license.

Now 310 file formats total (+22 video).

Install

Download SageThumbs2K-Setup-0.4.6.exe below and run it.

Windows may show a blue "Windows protected your PC" screen — the installer isn't signed with a (paid) certificate, as it's open-source indie software. Click More info -> Run anyway. Every line of the code is in this repo for you to inspect.
