post-built event xcopy fails with exit code 4

Question

my Xcopy fails to execute properly after I compile my project.

xcopy "$(SolutionDir)LuaModules\*.*" "$(TargetDir)Modules\" /S  /H /Y /C

Answer 1

You have unneeded slash after /S.

Answer 2

$(SolutionDir) gives the directory where the solution is in, but the project ($ProjectDir) gives the folder of your files. I had to use that instead
