Thought ProcessThe user is asking about disabling on-demand sync's behavior that's overriding their locally-generated thumbnails. Based on the context, it seems like they're dealing with Synology NAS and on-demand sync protocols that are interfering with their ability to generate custom thumbnails for file types that aren't supported by Synology. + +Let me first look at the files in the project to understand what they're working with, and then read the attached files to get more context about their specific situation. + +The project structure shows: +- autoThumbs.bat +- nascleanup.sh +- psthumbgen.py +- README.md +- run_thumbgen_prompt.bat + +This looks like a project specifically for generating thumbnails, likely for a Synology NAS system. Let me read the main files to understand the current implementation and the issue they're facing.
 + +--- + +I'll help you investigate options for disabling on-demand sync's interference with your locally-generated thumbnails.

Thought ProcessNow I have a good understanding of the situation. The user has a Python script (`psthumbgen.py`) that generates thumbnails for Synology Photo Station, and they're dealing with an issue where on-demand sync is overriding their locally-generated thumbnails. + +From the files I've read: + +1. The script generates thumbnails in a special `eaDir_tmp` directory structure that gets moved to `@eaDir` on the NAS +2. It supports various formats including videos (mp4, webm, etc.), PSD files, and Blender files +3. It uses a multi-tier approach: Icaros cache → Windows providers → FFmpeg fallback +4. The script is designed to work around limitations where Synology doesn't handle certain file types well + +The user's issue is that on-demand sync is destroying or overriding their locally-generated thumbnails, preventing them from generating thumbnails for file types that aren't supported by Synology or on-demand sync protocols. + +Let me search for more information about Synology on-demand sync behavior and see if there are ways to disable or work around this.

Thought ProcessNow I have a clearer picture. The user has a system where: + +1. They generate thumbnails locally using `psthumbgen.py` into `eaDir_tmp` directories +2.
