Hello Ewart
There is no "data" in the analysis, it is simply a definition of the file structures.
The actual data is in whatever folder you designate, so when you are in developer mode you can use the Project > Project description > Files option to point at a directory and use that data, which is really useful for testing.
For software that you release you either have the exe and the data files in the same directory or point to the correct directory using code such as hchangedir() or in the project definition you can set a default directory for the data.
Regards
Al
