I am running an instance of Nuxeo 5.5 as a virtual machine, and I've been testing out WebDav support on the Macintosh. When I open MS Office documents using the Finder and save them, the files are being duplicated with a ._ prefix. In other words, "TestFile.docx" becomes "._TestFile.docx" and "TestFile.docs" in Nuxeo. When I view these files in the Finder, they look fine, but in the Nuxeo UI, they don't. Is there any way to prevent this from happening?
