About the minimum recording unit
For recording a message, dividing a message, or creating a folder, the time
of the minimum recording unit is needed. Although the actual recording
time of a message may be less than that of the minimum recording unit,
the time of the message is counted as a minimum recording unit.
If the remaining recording time of the inserted "Memory Stick" is less than
that of the minimum recording unit, you cannot divide a message or create
a folder in the "Memory Stick".

About the maximum recording time and the maximum
number of messages or folders
A "Memory Stick" saves not only recorded messages but also the
information about division and the number of folders. Therefore, as the
number of messages or folders increases, the amount of memory in the
"Memory Stick" decreases.
The maximum recording time and the number of messages or folders
varies depending on this.
However, only in the case that you recorded up to the maximum recording
time, you can divide a message into three parts and delete the unnecessary
part in the message.
