stackoverflow on editor script.

Hey guys, I can't figure out why I keep getting a stack over flow exception error.

I've tried multiple ways to get this to work but just can't seem to figure out what is causing it to recursively keep overflowing.

(What I am trying to do is, copy folders from a specific place into Unity project). Almost have it, but can't grasp the Stack Error because I don't see how it's constantly running, perhaps I just don't understand enough about what's going on. Hope you guys / gals can help, until then, I'll be trying to figure this out more.

Here is the code.

(Editor GUI Button to run code).

 if (GUILayout.Button (FindRepo)) {
             FindRepository();
 
             ImportCulturalization(".", @".\temp", true);
             //ImportCulturalization(FolderPath, @".\temp", true);
         }

Now here is the actual code.

     private void ImportCulturalization(string RepoFolder,string destinationFolder,bool copySubDirs){
         string RepoFold = AssetDatabase.CreateFolder ("Codex-It", "Repository");
         RepoFolder = FolderPath;
         destinationFolder = RepoFold;
         string CodexFolderPath = AssetDatabase.GUIDToAssetPath (destinationFolder);
 
         // Here we import all the files if the Repository exists.
         DirectoryInfo dir = new DirectoryInfo (RepoFolder);
         if (!dir.Exists)
         {
             throw new DirectoryNotFoundException(
                 "Source Repository does not exist or could not be found: "
                 + RepoFolder);
         }
         DirectoryInfo[] dirs = dir.GetDirectories();
         // If the destination directory doesn't exist, create it.
         if (Directory.Exists(destinationFolder))
         {
             Directory.CreateDirectory(destinationFolder);
         }
         FileInfo[] files = dir.GetFiles ();
         foreach (FileInfo file in files) {
             string tempP = Path.Combine(destinationFolder,file.Name);
             file.CopyTo(tempP,false);
         }
         if (copySubDirs) {
             foreach(DirectoryInfo subdir in dirs){
                 string tempD = Path.Combine(destinationFolder,subdir.Name);
                 ImportCulturalization(subdir.FullName,tempD,copySubDirs);
 
             }
 
 
         }
 // I just added this to see if that helped - Nope.
         copySubDirs = false;
     }
