Created attachment 172578 [details] Comparison of how the same PDF file on local storage and sshfs are shown in Dolphin SUMMARY Dolphin doesn't recognize type of files without extensions on sshfs (possibly other remote connections too, will try later). Previews unavailable, "Type: Unknown" in properties, doesn't know how to open them STEPS TO REPRODUCE 1. Mount a remote directory using sshfs (works with both manual mounting and fstab) 2. Open the remote directory in dolphin, drop some files without extensions there 3. Notice how they don't have previews and opening them prompts for app 4. Add back original file extension and see how opening works fine now OBSERVED RESULT Dolphin shows the "?" icon and doesn't know how to open files on sshfs EXPECTED RESULT File type icons or previews are shown and files open in default apps SOFTWARE/OS VERSIONS Linux/KDE Plasma: NixOS unstable KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION I checked how pcmanfm, pcmanfm-qt and thunar work with sshfs and they appear to do what is expected, file types recognized, previews available where set up and opening works too
