## Properties

| Name | Read/Write | Description |
| --- | --- | --- |
| [Length](#length) | Read/Write | 4 These bytes contain a 4 digit numeric value that specifies the length of the Subfile in bytes.The segment terminator must be included in calculating the length of the subfile.A segment terminator = 1. Each subfile must begin with the two-character Subfile Type and these two characters must also be included in the length. |
| [Offset](#offset) | Read/Write | 4 digit numeric value that specifies the number of bytes from the head or beginning of the file to where the data related to the particular sub-file is located.The first byte in the file is located at offset 0. |
| [Type](#type) | Read/Write | 2 byte type of subfile, like "DL" |
