During OPCcalc installation the user selects a “Data path” and “Program Path”. The default locations are:
- Program path: C:\Program Files (x86)\Exele\OPCcalc
- Data path: C:\ProgramData\Exele\OPCcalc
You can check the location of your paths if you view the file %windir%\OPCcalc.ini (default is c:\windows\OPCcalc.ini).
The Data path contains all of your configuration data: libraries, library execution intervals, etc.
The Program path contains the installed OPCcalc applications: Equation Editor, Scheduler, etc.
If you back up the entire data path folders and files, you have a complete backup of your OPCcalc configuration. You can recover by installing the application and copying your data path into the installed data path.
