Content importer relies on info.magnolia.dirwatch.DirectoryWatcher detecting changes and it basically delegates those changes to user via Pulse. However, in case of copy pasting a folder to observed directory of Content-importer behaves wrong. The problem is being the folder identified but not the files beneath. However, when those files are changed then system is able to pickup those changes.

This issue most likely to be moved to Magnolia project will touch some code there however, since the cause is observable in Content-importer, it initially got created here. On the other hand, one has to start observing the content-importer module and its communication to info.magnolia.dirwatch.DirectoryWatcher for starting point as there might be small issue somewhere between the communication.
