filename?
"._" Files These invisible files are "resource fork" segments of files that are being created on the external volume. In Macintosh filesystems (HFS and HFS ) there is support for two types of file information: one is the resource fork, and the other is the data fork. The data fork will contain user-supplied information such as the text of a word document, and the resource fork will contain information about the document such as author, document-specific preferences, and other metadata.
