SUMMARY Right now, when you enable option to use custom view styles for directories, Dolphin creates hidden .directory file which is an issue by itself. But it also leads to complete inability to reset all customized settings. You need to reset them by manually deleting .directory file STEPS TO REPRODUCE 1. Enable option to customize directory properties 2. Change view style for directory OBSERVED RESULT Option to reset all of the custom styles and separate option to reset style for current directory to default EXPECTED RESULT No such options SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION Related issues: Bug 163705: Settings for directory should be in home directory and not in each directory as .directory Bug 322922: Dolphin should not store .directory files inside the actual directory to avoid cluttering and polluting the filesystem; should instead store this data in extended attributes
