I can not open STM32 project that I created in CubeIDE on MacOS on Windows CubeIDE.

Update! This project is opened without any problem on the latest version of Eclipse IDE for C/C++ Developers Version: Neon.3 Release (4.6.3) Build id: 20170314-1500.

You could also try to import by (ioc).

Mac and Win paths may differ at times.

@victagayun​ , as I mentioned above, project is opened on Eclipse (on Windows). And I'm sorry, I was not so detailed, project is not just .ioc, it is project with some bunch of code already.
