This is a general Eclipse thing, not specific to STM32. The .project is the Eclipse project file while .cproject is specific to the CDT (C and C++ plugin).

They're also plain text files, so you can open them in a text editor to find out.

But despite pain text advice is to avoid udating them by hand ... as part of tool metadata who knows drawbacks ...

I didn’t suggest editing them. But you can look to see what they are and what’s stored inside.
