The version chunk defines the version of the collection of sounds. This version is used when installing DLS files and replacing old DLS file versions with a new one. A version chunk is not required in a DLS file.
The version chunk in the DLS file format has the following structure.
| Byte sequence description | Length in bytes | Starts at byte in the chunk | Value |
| chunk ID | 4 | 0x00 | The ASCII character string "vers" |
| size | 4 | 0x04 | The size of the chunk in number of bytes (unsigned integer) less 8 (less the size of "chunk ID" and the "size"). The size of this chunk is always 8 |
| high order 32 bits of the version | 4 | 0x08 | The top 32 bits of the version |
| low order 32 bits of the version | 4 | 0x0C | The bottom 32 bits of the version |
The format of the version follows the format of versions in Windows executables and dynamic link libraries. For example, in the version "1.0.1.10", the first two numbers will form the hexadecimal value 0x00010000 for the top 32 bits and the last two numbers form the hexadecimal value 0x0001000a for the bottom 32 bits.
