Right click in the right window panel, without selecting a folder..., I get the below
Vainly tried to figure out where in Opus I could edit this, adding an entry or deleting one.
e.g. the "FolderTimeUpdate" - probably I have used this once, or installed something, but I have no idea where to find it in Opus.
(Went thru Settings > File Types, but could not find it)
Already looked there, even when selecting 'All' at the top, 'Search Everything' or 'Voidtools' do not show up, so I assumed they might be hidden somewhere else.
Ah, right, thank you! Matter solved.
I was vainly seeking for a button to 'Add' (New) something to the Context Menu, i.e. similar to Settings>File Types>All files and folders> Edit.
However, I should use Customize > Context Menus > Edit and -then- copy some already existing command in there.
Thanks again.
