This is a recent occurance. The word lock in front of my documents will not let me access them or alter them.
If you are talking of the .~lockFileName.Ext files: They don’t contain your documents. Everyone has 1 KiB. They are created in the same folder to protect files against being opened a second time. They are killed again as soon as the working files are closed correctly. If LibO or the OS crashes this will not be done. You need to delete these files manually then.
