Problem extracting XMP info from \\fileserver\sharename\filename.len
java.lang.Exception: No size information found. (File produced by unknown)
Solution
Problem is caused by LEN files generated by Nexus missing the XMP information. Device Manager supports only LEN files from FlexRip or Imaging Engine where the XMP information is included.
