Instead of starting LO, i.e clicking on a generic icon, start the component you intend to use: Writer, Calc, Impress, … because you know tou’ll edit a text document, a spreadsheet, an presentation, … When the component opens,
Recent Documents will present the list of recent file names.
Remember that this list is only a cache for your recent activity. If you moved a file or deleted it outside of LO, the name will no longer point on the designated file. This is not LO fault. This was done without LO knowing it.
