Opening a file with filename
foo with LibreOffice creates, at least on my system (Debian Jessie, Openbox, no Desktop Environment, Thunar) a file named
.~lock.foo#, apparently as a means of flagging that it has the file open. When LibreOffice is closed, the new file is deleted. So far, so good.
But this file creation and deletion results in the Date Modified attribute of the enclosing folder being updated to the present, even if the no actual changes have been made to any of its contents.
So here's the question: How can I either get LibreOffice not to create a lock file in the same directory as the file being edited, or suppress the updating of the folder's Date Modified attribute under those conditions.
