how to unlink libre DB from Access

When opening Access, a Libre DB shows up in File Explorer. When I close the Access DB, the Libre DB file disappears from File Explorer? how do I unlink Libre from the Access DB file

The question was asked on IRC; the additional details were:

this is a window message I get when trying to delete the file from File Exolorer "Document file ‘Genesis224 Order Database Master.ldb’ is locked for editing by:

Unknown User

Open document read-only or open a copy of the document for editing."

here is the file name in Explorer Genesis224 Order Database Master.ldb"

So the answer is: that is not “a Libre DB”; it’s MS Access lock information file - see Description of LDB File - Office | Microsoft Docs. Possibly you had associated ldb files with LibreOffice - but in fact, they are not related to it. The file is used by Access, so you can’t delete it, naturally.
