7.2.5 Data Directory Lock
HydroSoft now protects the data directory by a lock. Once an instance of HydroSoft is working on a
data directory no second instance of HydroSoft can operate on the same data.
This locking is introduced to keep data integrity in case a user is running HydroSoft and a back-
ground instance of HydroSoft (started via the Windows task scheduler) also tries to work on the
data.
HydroSoft will exit with a return code of 2 if the data directory is locked.
