It is better to chose one format for all your discs. Format D1 provides maximum compatibility with software such as disc editors, while D10 provides maximum storage space. D20, which sacrifices a little storage space to provide twice as much directory space, is the default format, but this default can be changed by using function 3. To use different formats with the CP/M versions, see the relevant notes below.

The Buffer format is needed for function 8 (see below). The "Other" option allows you to define your own format. within sensible limits.

When using 256 directory entries, never allow more than 140 files per User group. For further information, see the Technical Details below.
