Php source access

when i use the SaveFileDialog function, my php files is revealed inside the Data directory.
if user (in savefile dialog) copy all the php files to other folder, the user can access my php source code.
there is a solution?

Yes, there is a solution. Enable “Use an absolute path for the virtual “Data” subfolder:” option

And use a virtual path beginning with with some letter such as X:\ or Y:\
