The configuration tool allows you to select which video formats to support and how to generate the thumbnails (e.g., using the first frame, or a frame from a specific time) [1].

It is designed to be a lightweight tool that adds functionality without significant system impact [1].

Features a "cache cleaner" to clear old, corrupted thumbnail caches in Windows, helping to refresh and speed up file browsing [1].

Ensure you download this, or any self-extracting executable ( .sfx.exe ), from a trusted source, such as the official developer site or a reputable software repository, to avoid malicious software.
