When I attempt to import an NCD file into the PlanAhead project, the following warning occurs:
"WARN: [HD-PAR 0] Cannot Open File : <path>/<file>.ncd"
The NCD is not imported and no error message is present.
This can be caused by limited space in the directory where the temp files are written. In Linux or the command line, the temp files are stored in the directory where PlanAhead was invoked. In Windows, they are written to the directory the GUI tells PlanAhead to start in.
Currently, there is no way to change the output of these temp files, so you must free up space in these directories.
