record organization or file structure not supported by FAT Facility: EFI$CP, The OpenVMS EFI Partition Control Program Explanation: The target file has an RMS record format or file structure that is not supported by FAT, nor by operating systems or environments or applications typically accessing files on FAT volumes. As a result, the file contents are unlikely to be easily accessable within these environments, and may or may not be viewable by or by accessable these applications. It is unlikely that the record attributes and file structures will restored correctly should the file be subsequently copied back onto an OpenVMS disk, as well; the record attributes and details of the file structure may or will be lost. While most any modern platform does support one or more sequential file formats, there can be and often are record-level differences within the bytes associated with a particular sequential file storage format on a particular platform. The file record format for the specified file is expected to be unique to OpenVMS. Files using block formats, or files of Stream or Stream Linefeed record formats are generally the most compatible formats across the most platforms. This message is only generated when copying file(s) from an OpenVMS volume structure onto a FAT volume structure. User Action: No particular user action is required, though the conversion to and the use of a record format supported more directly by applications using FAT would certainly be recommended. You can protect OpenVMS structures using a zip archive to protect the attributes, or you can potentially restore the attributes by using either CONVERT/FDL or SET FILE/ATTRIBUTES to restore lost record attributes on any files imported back into OpenVMS.
