If you do not like to use projects you can use this alternative. Using Explorer is a handy and quick way for copying directory structures. It uses a similar approach as the way Explorer itselves copies and pastes folders.
You first have to enable Explorer in the program and then you can right-click in Explorer to 'OnlyDirCopy' and 'OnlyDirPaste'.

• How to enable:
  Choose 'Explorer - enable' to toggle between enable and disable. Enabling means adding extra commands to the Explorer context menu, disabling means removing the commands. When you close OnlyDirCopy this status will be saved
  
  
• How to copy:
  Open Explorer and look for the folders you want to copy. Right-click with the mouse on the root of the folders and then choose OnlyDirCopy.
  
  
  Then choose the folder you want to copy to and right-click OnlyDirPaste!
  The program OnlyDirCopy will open and you will see a preview and get the chance to cancel or run. If you choose to run then the job starts. You can eventually follow the actions using the reporting features.
  
  
• Explorer options:
  - Auto close: when pasting, the program will close after the run is completed.
  - Remember source: when the program closes, the source will be remembered.
  That way you can OnlyDirPaste several times to several locations without each time having to right-click OnlyDirCopy first.
