Windows Explorer ~ 20 % but Dopus uses 100 %
100% of what, measured where, while doing what?
Lowering Preferences / File Display Modes / Thumbnails: Thumbnail threads may reduce the disk usage while generating thumbnails, if that's what you mean, and you'd prefer the operation was CPU-bound rather than disk-bound. Full resource utilisation isn't always a bad thing, though (if something is only using 20% of the resource, it may be under-utilising it and running slower than it could).
Opus has to read files to generate thumbnails for them. That means using the disk.
High disk usage isn't automatically a bad thing if there is a reason for it.
If both disk and CPU were not close to 100% while generating thumbnails then it would mean thumbnail generation was taking much longer than it has to by not using all the available resources to get as much done at once.
You can reduce the number of thumbnail threads (see my reply above) if you'd like Opus to generate fewer thumbnails in parallel. Sometimes that can be faster, for example if so many things are being read at once that the filesystem is "thrashing" as it tries to service the requests. But it may also make things slower.
I usually set the number of threads to be the number of logical CPU cores, minus one or two (leaving some CPU free to handle other work and keep everything else responsive, but not much since Windows can usually share things out as needed).
Thank you for your detailed explanation.
But others file manages and windows explorer don't have so much disk usage.
I turned it off.
Do they generate as many thumbnails as quickly? Disk usage is only part of the picture. High disk usage may be good or bad.
ok ,look vid.me/wUKk
windows explorer vid.me/8u6t
Explorer looks like it is using cached versions of the video thumbnails, while Opus seems to be generating them.
Is thumbnail caching turned on within Opus? (Preferences / File Display Modes / Thumbnails)
You may also want to try going to Preferences / Viewer / Viewer Plugins, then configuring the Movie plugin and turning off its Generate Thumbnails option. Opus will then fall back on the Windows shell for video thumbnails, which can be better (or worse) depending on the codecs/splitters involved.

thank you , now it's fine
i need help, i couldn't figure out how to do this !
That option doesn’t exist in Opus 13 (it’s always off now, effectively).

i have a folder that has thousands of .ts recorded streams that i have to sort through daily, and it's difficult doing that when dopus is utilizing 100% of the disk while i'm inside that folder, i'm suspecting that it's generating thumbs or doing something that i must turn off to make it not utilize 100% of the disk.
It’ll only generate thumbnails if you’re in a mode which displays thumbnails. Use another mode (e.g. Details) if you don’t want thumbnails.
it's already in "View" details mode but maybe it's generating thumbs for the viewer pane ?
It's probably not due to thumbnails in that case.
Which columns are displayed?
Does the disk usage only start when you go into that folder?
What happens with the same folder in File Explorer?
i have a duration column added to the default columns but it takes less then a minute for all files durations to display and the wheel stops turning when that happens, right then the disk usage should drop to 0% but for 15 minutes or more it keeps at 100% and in resource monitor i find at least 10 instances of dopus each reading a separate file in this current folder.
windows file explorer takes less then a minute to display the duration of each file, after that the disk usage drops to 0 and i start working on those files.
If you link your account and send some process snapshots while that's happening, we should be able to use those to at least explain why it's happening, and hopefully solve it as well (depending on the cause).
problem is solved after installing everything by voidtools alpha version, now it takes close to 20 seconds for the disk usage to drop to 0 , what a huge difference.
In that case I'd say you have it set to calculate folder sizes automatically. You can turn that off if you don't want it to.
