SUMMARY Say you are a network admin and you have multiple KDE/Dolphin users working with network directories containing images/videos and multiple people try to access a directory which they have not accessed before. For each of the users their respective Dolphin/KIO instance will scrape the directory and generate user-local previews. This pounds the network server to a halt due to the preview generation I/O. Right now Dolphin has 2 operational modes based on user preferences neither of which help because users have to interact with the images: 1. Don't create previews at all 2. Create previews below a certain size As per Thumbnail Managing Standard it is possible to crate a hidden .sh_thumbnails directory which will contain the thumbnails for the directory. Would it be possible for Dolphin/KIO/KDE to implement the .sh_thumbnails part of the Thumbnail Managing Standard? STEPS TO REPRODUCE 1. Have remote location previews generation enabled 2. Delete local thumbnail directory 3. Visit a network location with a lot of image/video files OBSERVED RESULT Dolphin/KIO recreates the thumbnails for the files located in the network dir. Thumbnails are created in the local thumbnail directory. Thumbnail creation is slow for a large number of files because it is single threaded. EXPECTED RESULT Dolphin/KIO should offer the user the option to create the .sh_thumbnails directory in the network location or it should automatically create such a directory if the user enables such an option.

>or it should automatically create such a directory if the user enables such an option. That's not what the spec says: "This is a read-only collection of thumbnails" We can still implement the spec if we don't already, but to solve your use case you'll need some server side daemon populating it.
I can confirm we do not implement it currently.
