Copy or Move Folder Structure in SharePoint Using CSOM

This post is intended for SharePoint Online and 2016+ using CSOM.

In previous version of SharePoint, moving a folder structure to a different library or a different library in another site collection required a good amount of code and effort. With the introduction of Microsoft.SharePoint.Client.MoveCopyUtil we now have the ability to use methods like MoveFolder to perform a cut and paste of a folder structure. There are other methods that are worth exploring like FolderCopy that is a copy and paste of a structure.

More methods can be found here: MoveCopyUtil members

Name Description
Public method Static member CopyFile
Public method Static member CopyFileByPath
Public method Static member CopyFolder
Public method Static member CopyFolderByPath
Public method Static member MoveFile
Public method Static member MoveFileByPath
Public method Static member MoveFolder
Public method Static member MoveFolderByPath

Example of moving a folder between site collections.

string dstUrl = "";

using (ClientContext srcContext = new ClientContext(dstUrl))
  string sourceFolder = "";
  string destFolder = dstUrl + "libraryname/foldername";

  MoveCopyUtil.MoveFolder(srcContext, sourceFolder, destFolder);

Again, this is using CSOM with the latest version of the NuGet package (16.0.4351.1000).

  1. Hi, I was googling copying folder structure to SharePoint and I found this page. However, in my particular case, I want to copy a folder structure form a shared folder location in my local network.
    Can you please tell me if there is a similar procedure that uses the shared folder path \\server\shareFolder\folderStructure to copy the folder structure to a SharePoint library?

  7. Hello,
    I just tried your simple code in my SharePoint OnPrem environment. “MoveCopyUtil.MoveFolder” is working in same site collection. But When try the move folder diffrent site collection, I am getting this error
    Message=MountPoint security error: NoScript isn’t enabled on the host site
    at Microsoft.SharePoint.Client.ClientRequest.ProcessResponseStream(Stream responseStream)
    at Microsoft.SharePoint.Client.ClientRequest.ProcessResponse()
    at Microsoft.SharePoint.Client.ClientRequest.ExecuteQueryToServer(ChunkStringBuilder sb)
    at Microsoft.SharePoint.Client.ClientContext.ExecuteQuery()

  8. It looks like the error points to your problem.

    The error message suggests that the NoScript feature isn’t enabled on the SharePoint host site, and this is causing a security error. This could be restricting the operation you are trying to perform with MoveCopyUtil.MoveFolder.

    Here are some steps you might consider:

    1. **Contact Admin**: You’ll likely need administrative privileges to change this setting. If you’re not the admin, reach out to them.

    2. **Enable NoScript**: If you have admin access, you might need to enable the NoScript setting for the SharePoint host site.

    3. **Review Permissions**: Ensure that the user or service account running the operation has the necessary permissions to perform the task.

    4. **Update Code**: If you have control over the code invoking MoveCopyUtil.MoveFolder, make sure it adheres to the security policies set by the host site.

    5. **Consult Documentation**: Check Microsoft’s official documentation for specifics on the NoScript feature and how it affects operations like MoveFolder.
