Created attachment 169974 [details] Screencast showing "disappearing" file SUMMARY Dolphin does not seem to show files with the file extension ".old" (and possibly others?) STEPS TO REPRODUCE 1. Rename any file by appending ".old" to its current full name OBSERVED RESULT Dolphin does not show the file any more. EXPECTED RESULT The file should be shown with its new added extension. Dolphin should not make any files invisible, independently of their extensions. It should only hide "invisible" files, i.e. the name of which starts with a dot, if the corresponding view menu option is checked. (Which it wasn't in my case.) SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE neon (available in About System) KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 ADDITIONAL INFORMATION See attached screencast. The bug causes confusion by not showing files which are actually there, and may even be mis-used to actively hide information from the user.
Dolphin can be configured such that when it is not showing hidden files, it also doesn't show "backup" files ... see the "General" tab of the View configuration pane "Also hide backup files while hiding hidden files". Do you have that selected?
Created attachment 169980 [details] Dolphin Config Dialog Screenshot (View Pane) Ok, enabling "hidden" files shows these entries. But actually I cannot find the config option you mention, see attached screenshot - I also clicked to the other panes in the config dialog and wasn't successful. Once I found the option, I will close this issue as "INVALID" / "Layer 8 problem".
Created attachment 169983 [details] Also hide backup files option This is the configuration option I was referring to. You don't seem to have that option, I don't know why, maybe someone else can advise. I'm using Dolphin 24.05.0
Ok, curious... Unfortunately, KDE neon currently does not seem to provide a more recent Dolphin version. Nevertheless, it should be configurable in any case, also in my version, as it's a somewhat "surprising" behaviour. (Who actually decides which extensions are considered as "hidden" files - is it hard coded or also configurable? It will surely be heavily dependent on the user's locale?)
Sorry, the tool-tip says "Backup files are the files whose mime-type is application/x-trash, patterns: *~, *%, *.bak, *.old, *.sik". I think we should mark this bug as fixed on the grounds that the behaviour is optional in later versions of Dolphin? Reopen if you disagree.
