If there is a more appropriate forum or support contact could you please give me the details. Regards, GrahamRe: Microsoft Tape FormatThanks Tejashree but I'm actually looking for a complete specification which would include the detail of all the block / stream types. I have a document for version 1.0 which spans 117 pages which I found at www.layton-graphics.com/mtf/MTF_100a.PDF, it is the latest version of this that I am trying to locate. Regards, GrahamMicrosoft Tape FormatHi, I am trying to locate a full specification for the Microsoft Tape Format, I have a copy of a document covering version 1.0 but this does not include XP / 2003 Operating System specifics. Can you help please? Many Thanks, Graham
