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.ServerRelativeUrlfolderUrl); 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; } }
