 Orphaned Documents
 ------------------
 
 In the event the editor crashes or otherwise exits without saving the project state, files that have been added to the project tree and are saved to disk will appear in a special "Orphaned Items" root folder next time the application is started.
-These orphaned files will not have any meta data associated with them, so the label and other information will have to be set again, and the files moved back to the correct location in the project.
+These orphaned files will not have any meta data associated with them, although novelWriter will try to restore the file label it had in the project tree. Other information will have to be set again, and the files moved back to the correct location in the project.
+
+Project Lockfile
+----------------
+
+To prevent orphaned files caused by file conflicts when novelWriter projects are synced with file synchronisation tools, a project lockfile is written to the project folder.
+If you try to open a project which has such a file, you will be presented with a warning, and some information about where the project is potentially open.
+You will be give the option to ignore this warning, and continue opening the project.
+However, if multiple instances are in fact editing the same project, you are likely to cause inconsistencies and create diverging project files.
+
+.. note::
+   If, for some reason, novelWriter crashes, the lock file may remain. If so, it is safe to ignore the lock file warning when re-opening the project.
