@ChrisW67 Sorry , I panic ( I had multiple problems , mainly with OS ) and switched to only HDD I have which will run Ubuntu... I am currently using updated QT ( 6.2 ?) and after I tried to build a new , test project I have now CMakeLists.txt and NO .pro file .

I have never seen xx.txt before , always had .pro file .
Is that something new?

Qt Creator allows you to use a range of different systems to orchestrate building your project. You are used to
qmakeand its PRO (project) file, but the project you have there is usingcmakewith the CMakeLists.txt configuration file.Qt 6 itself is built using cmake rather than qmake. You can choose to use either for your projects at the moment but CMake is recommended for the longer term.
