mdm.FileSystem.copyFolder will silently fail to copy folder if source/target folder paths end with backslashes.

var sourceFolder:String = mdm.Application.path+"my_folder\\";
var targetFolder:String = mdm.Application.path+"target_folder\\";
mdm.FileSystem.copyFolder(sourceFolder, targetFolder);

Above won't result in my_folder copied into target_folder.

The desired feature support seems to be supporting both version of paths no matter if they ends with trailing backslash or not (the path/folder name should be valid - that is do not contain reserved characters and does not end with space or dot).

To repeat compile and run provided sample. The "copy" button should initiate mdm.FileSystem.copyFolder method that should copy included folder into new one within project root directory.

The sample code contains helper method that could be used to convert paths that are returned at runtime from other {mdm} script methods like mdm.Dialogs.BrowseFolder, etc:

function $$(path:String):String
{
if(path.length > 1 && path.lastIndexOf("\\") == path.length-1)
{
return path.substr(0, path.length-1);
}
return path;
}

that could be used as:

mdm.FileSystem.copyFolder($$(sourceFolder), $$(targetFolder));
