Change folder structure of project source files

Is it asking for problems making the folder structure of my source files more granular or is it just open project and point Passolo to the new location(s)?

Additional info: I changed the structure and Passolo doesn't find the source files and it looks as if I have to change the path manually for each and every one? That's not a workflow but a pain ...

Any suggestions how to change the path for some hundred source files?
