Created attachment 131154 [details] video SUMMARY The folder mounted by kde-connect is not considered a remote folder by dolphin (since it is mounted through sshfs), so thumbnail generation is done even if the option to ignore remote files is active. STEPS TO REPRODUCE 1. In kde connect settings in android, add a folder with many videos or images to the sharing list (or add files to the currently shared folder). 2. Access this folder through dolphin OBSERVED RESULT This makes dolphin extremely slow when a folder with many files is accessed. Like a folder with many photos and videos. EXPECTED RESULT An option in the configuration menu to disable previewing in specific folders. Or this could be identified and done automatically. The first option seems to be the ideal one because it would avoid future problems in case of changes in kde-connect. Operating System: Arch Linux KDE Plasma Version: 5.19.4 KDE Frameworks Version: 5.73.0 Qt Version: 5.15.0 Kernel Version: 5.8.3-arch1-1 OS Type: 64-bit
In fact you already can! :) 1. Dolphin settings > General > Remember display style for each folder 2. Go to the folder you want to turn off previews for 3. Hamburger menu or View menu > uncheck > "Show Previews"
Thanks, Nate. It really works. But it bothers me to have this option activated. I like that the changes made in Dolphin, like the order and type of display, hidden folders, thumbnail size are applied globally. Individual settings may be nice at first, but after many specific settings are accumulated for each folder, it becomes difficult to manage. I still think my initial suggestion is a better way to handle this, I don't think marking it as "resolved" is correct. btw, even with preview disabled, the problem of slowness continues. I think the problem is much "deeper" than that. Maybe it's some problem related to sshfs, because I use remote sftp folders and they work very well. i tried to inform myself with the developers of kde connect but they don't seem to be worried about it. It's been a while since its development has been declining and so has the quality.
Yeah, I understand that this manual action is kind of a workaround, not really a perfect solution. Handling this case automatically would require one or more of the following: 1. Automatically disable previews for sshfs mounts (not ideal since some can be fast enough 2. Automatically disable previews for slow filesystems (requires detecting slowness; potentially technically challenging 3. Speed up kde-connect's sshfs mount (probably ideal, but probably technically challenging or else it would have already been done)
> 1. Automatically disable previews for sshfs mounts (not ideal since some can be fast enough It would seem the expected behavior (disregarding if the connection is fast or not), because the problem is that the option "Skip previews for remote files" being set implies, well, no previews for remote files and an sshfs connection is "remote". P.S.: Is there a reason this report is closed as a WFM? From the discussion it seems all participants acknowledge existence of the problem
> 1. Dolphin settings > General > Remember display style for each folder I should mention I'm not certain this workaround works that well, because 1. As part of path to the dir mounted by `kde-connect` I see some ID, which I am not sure specific to what (device, the connection, the PC, or is it even randomly generated?), so I presume setting local style may break if it changes 2. There may be more than one folder and having to set style for each is inconvenient.
