Qt Strange size!

So If I have Debug, it requires full libs, If Release then this "stripped" files ?? I am right ?

No, the release are "full" too

The debug versions are bigger because they have much more "debugging" information, so that they are easier to debug, you use the debug version on your computer to test and find bugs, and the release build when you send the application to your clients.

And the release executable is optimized for better performance.
