4.2. Session management
To simplify management, survey data is divided into survey runs, and each session is in
turn broken down into sub-divisions as decided by the user, either according to travelled
distance, elapsed time, or number of pings.

4.2.1. Automatic sessions
These sessions may be managed automatically. In this case, a new session directory is
automatically created each survey day, with the name RUNi, where "i" is the number of
the day counted from the beginning of the survey.
For example, the RUN005 directory contains all of the data acquired during the 5th day of
the survey.
An empty file, called RUNi.HAC is also created at the same level than the RUNi
directory. When you will select this empty file during survey, you will replay
automatically all the files of the session. It is the only use of this file.
This operating mode makes it possible to operate the software without operation
throughout the survey. It of course allows the software to be started and stopped
repeatedly during the survey.
4.2.2. Manual sessions
In this case, a new RUNi directory is created whenever the archive is started, except if
you wish to continue working in the current directory after an incident in this case you
must choose “Restart with previous”.
