Storage Daemon File Output Format

The file storage and tape storage formats are identical except that tape records are by default blocked into blocks of 64,512 bytes, except for the last block, which is the actual number of bytes written rounded up to a multiple of 1024 whereas the last record of file storage is not rounded up. The default block size of 64,512 bytes may be overridden by the user (some older tape drives only support block sizes of 32K). Each Session written to tape is terminated with an End of File mark (this will be removed later). Sessions written to file are simply appended to the end of the file.
