3 months ago the ../ is inserted here https://github.com/elfbutt/koreader-coverbrowserclean/blob/a7d1e4f816922d9acf25e15c7c6a8e0ab694f9ac/frontend/ui/widget/filechooser.lua#L445
Should be able to intercept the call of that function, run it, and then remove the item from the list afterwards.
Note how this example intercepts, runs code, and then runs the original afterwards. https://github.com/elfbutt/koreader-coverbrowserclean/blob/a7d1e4f816922d9acf25e15c7c6a8e0ab694f9ac/plugins/coverbrowser.koplugin/main.lua#L681
"if you have a folder that contains exactly as many books as you have coverview set to display items per page, it says there's a page 2 of books but there's not, it's empty
presumably it would do the same for book counts divisible by items per page too
if that navbar footer with the page counts and << < > >> buttons is in coverview, it's an easy fix. if that footer is drawn the same as the titlebar... very less easy"
due to removal of ../ menu item without forcing a recount of list menu items
