Copy all folders in a library to another library

Hi Agolla,

Hope the below would help you to move the files from source folder to destination folder

public static class FolderExtensions

{

public static void MoveFilesTo(this Folder folder, string folderUrl)

{

var ctx = (ClientContext)folder.Context;

if (!ctx.Web.IsPropertyAvailable("ServerRelativeUrl"))

{

ctx.Load(ctx.Web, w => w.ServerRelativeUrl);

}

ctx.Load(folder, f => f.Files, f => f.ServerRelativeUrl, f => f.Folders);

ctx.ExecuteQuery();

//Ensure target folder exists

EnsureFolder(ctx.Web.RootFolder, folderUrl.Replace(ctx.Web.ServerRelativeUrl, string.Empty));

foreach (var file in folder.Files)

{

var targetFileUrl = file.ServerRelativeUrl.Replace(folder.ServerRelativeUrl, folderUrl);

file.MoveTo(targetFileUrl, MoveOperations.Overwrite);

}

ctx.ExecuteQuery();

foreach (var subFolder in folder.Folders)

{

var targetFolderUrl = subFolder.ServerRelativeUrl.Replace(folder.ServerRelativeUrl,folderUrl);

subFolder.MoveFilesTo(targetFolderUrl);

}

public static Folder EnsureFolder(Folder parentFolder, string folderUrl)

{

var ctx = parentFolder.Context;

var folderNames = folderUrl.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);

var folderName = folderNames[0];

var folder = parentFolder.Folders.Add(folderName);

ctx.Load(folder);

ctx.ExecuteQuery();

if (folderNames.Length > 1)

{

var subFolderUrl = string.Join("/", folderNames, 1, folderNames.Length - 1);

return EnsureFolder(folder, subFolderUrl);

}

return folder;

}
