I've turned off caching of thumbnails in Windows 10
so that File Explorer only displays the icons associated with a file type (I don't want Thumbs.dbs created all over the place, as well as it being an improvement to privacy). Unfortunately, this also means no thumbnail generation at all in File Explorer (according to my experience and searches). Edit: It's possible to just turn off the caching and still have thumbnail generation (via Group Policy Edit).
I recently discovered Icaros and would like to use it as my thumbnail generator due to it functioning even without a cache (though I do plan to whitelist some folders). Opus can generate without caching too, but it lacks some features and support for files that make Icaros the better choice for me. If I could disable Opus from generating thumbnails, it'd simplify things by being able to assume any that are seen are of Icaros' doing. The problem is, I can't find a way to do so.
Is it possible to turn off all thumbnail generation? For example with Icaros inactive, some MKVs I have display will still display a thumbnail, whereas others will not: when I quickly compared these, the videos inside didn't differ much other than by bit depth, 8 vs 10 (thumbnails vs no thumbnails) - Edit: File Explorer behaves the same way. When I activate Icaros, the thumbnails that Opus was generating get replaced with those by Icaros (hopefully Opus isn't doubly doing the work in the background).
I've tried disabling all the plugins via Preferences, but Opus keeps generating thumbnails. If I could disable image thumbnails too, Icaros could handle their generation as well (from what it looks like, but it's hard to tell if image thumbnails are getting replaced -- unlike videos which have different frames generated as their thumbnails).
Ideally, Icaros could handle all thumbnail generation and caching, and Opus would do nothing but display what Icaros has requested for generation.
