CW3 crashed Windows Explorer , if I delete my project when having same project folder open in Windows Explorer.
I don't think it's good thing , so can you do something about it?
You know what caused it. Just don't do that.
Yeah , but I sometimes have accidently project folder open and then I forget to close it before removing it project from game.
Is this bug possible to repair?
Yes, since it's Windows Explorer that crashes, I suggest you report it to Microsoft and ask them to repair Windows Explorer. Or provide the log or crash data that proves it is a bug in Creeper World.
What if game could know project folder of project
what you are deleting is open
when trying to delete and says you to close folder before deleting?
This is just suggestion , no need to do anything about it.
CW3 just calls the mono routine for deleting a file, which in turn calls the OS API for deleting a file. If explorer is crashing then it is likely some OS or explorer extension you have installed (you might not even know it) that is causing explorer to crash. There isn't a lot CW3 could do about it... if the file/directory were actually locked then the OS level delete call would fail rather than explorer crashing.
