ISO/IEC 13346 specifies a format and associated system requirements for volume and boot block recognition, volume structure, file structure and record structure for the interchange of information on media between users of information processing systems.

The media shall be recorded as if the recording of sectors may be done in any order.

This International Standard consists of the following five Parts:

Part 1: General

Part 2: Volume and Boot Block Recognition

Part 3: Volume Structure

Part 4: File Structure

Part 5: Record Structure

Annex A - ICB Strategies, is part of this part of ISO/IEC 13346.

This part of ISO/IEC 13346 specifies a format and associated system requirements for file structure by specifying:

• the placement of files;
• the attributes of the files;
• the relationship among files of a logical volume;
• levels of medium interchange;
• requirements for the processes which are provided within information processing systems, to enable information to be interchanged between different systems; for this purpose, it specifies the functions to be provided within systems which are intended to originate or receive media which conform to this part of ISO/IEC 13346.
