+README File provider
+
+This is a sub-plug in for the VDR UPnP/DLNA media server plug in.

+
+Description:
+
+The file provider provides access to any files on the file system. It
+scans all files, which listed in the directory configuration file of
+the sub-plug in.
+
+It provides the following URI scheme:   file://
+
+Additionally, it is used to access the files for streaming.
+
+The provider implemented the seekable interface and therefore allows
+seeking in the files via byte based seeks.
