[PNaph.2]

Hi team, I am using touchGFX in project, I would like to know how can I add user defined files or folder in to touchGFX project?

I tried to add folders but the files present in the folder not compiled.

I also tried to add this files to include path in project properties but this not worked for me.

Please someone tell me how can I do this.
