Just like web browsers or music players. e.g.: archive.zip - Ark Reproducible: Always
Thanks for reporting. Indeed Ark's window title is not consistent with other KDE applications'.
Btw, Ark does show the archive name in the title when you open it from Ark itself. However, it doesn't when you open the archive from Dolphin, so this is a bug rather than a wish.
Git commit c9de2b68460e7fbd7de34fafcd2197f83b72802b by Elvis Angelaccio. Committed on 01/02/2016 at 17:56. Pushed by elvisangelaccio into branch 'Applications/15.12'. Always show the archive's name in window title When opening an archive from Dolphin, the '-qwindow %c' argument was overwriting the archive's name. This was also redundant, as the string 'Ark' is already automatically added to the window title.
