How do I delete a file in Libre Calc

I do weekly itineraries on Calc and want to delete the old ones. Should I just do it in downloads or my documents?

How do I delete from Libre Calc?

You don’t delete files in LibreOffice (unless you use a macro or extension), use your operating system’s file manager dialog to delete files. Or I misunderstood your question…

And if the file still shows up in the LibreOffice window showing recently opened files, simply click on the little “X” in the upper right-hand corner of the icon to delete it.
