trying to copy a whole folder, but when i do this:
The best solution for me was to use the magic XCOPY as I had to copy all files and sub directories
$(ProjectDir)\lib
$(ProjectDir)\..\..\Something\lib
$(SolutionDir)\Something\lib
This build event is fired once build succeed, it cleans the FilesDestination folder then it copies all files with directory structure from FilesSource to FilesDestination and then it delete the FilesSource folder to keep everything "bien propre" :)
NOTE
For FilesDestination, make sure you use the Condition attribute or remove it to have the copy process to its end
