MarsSeed [1] filed a deletion request for kde-servicemenus-unarchiver [2]: I suggest this old .desktop link from 2015 intended for KDE's default Dolphin file manager and the Unarchiver CLI package last updated in 2020 can be safely deleted. Today the Dolphin file manager works perfectly with KDE's default archive manager tool, Ark, which supports a wide range of archive file formats and it even has multiple alternative optional dependencies that support the LZO format specifically. Unarchiver is not the best choice for that IMHO, because it is unmaintained. But Ark can directly use the Unarchiver package from Arch, one only has to install the latter as an optional dependency, no other setup needed. With Ark installed, Dolphin file manager's file/directory context menu offers Compress and Extract options (where relevant). Therefore this old plug-in link package is more limited that what KDE today offers by default, in terms of archive file support.
