I came across a post from last year where someone was trying to access a file in the FileCabinet.  NS Emps. responded that it wasn't possible (at the time).  I was looking through the latest WS docs and came across some stuff that makes me think it might be possible to work with the file cabinet via web services.

I banged out this code real quick to try and save a file.  This code is returning error:

The record type [file] is invalid.

 using NSFile = NSWS_test.com.netsuite.webservices.File;    private void button1_Click(object sender, EventArgs e)  {      OpenFileDialog fileDlg = new OpenFileDialog();      if(fileDlg.ShowDialog() == DialogResult.Cancel)      {          return;      }        try      {          //  Load the file          byte[] data = FileUtils.ReadWholeFileBytes(fileDlg.FileName);          Guard.ReferenceNotNull(data, "Failed loading file data");            //  Create the NetSuite file record          NSFile file = new NSFile();            file.content = data;          file.createdDate = DateTime.Now;          file.createdDateSpecified = true;          file.description = "Sample File added from Windows Application for testing purposes";          file.fileSize = data.Length;          file.fileSizeSpecified = true;          file.fileType = MediaType._PLAINTEXT;          file.fileTypeSpecified = true;          file.name = "Sample File From Desktop Application";            //  Create the folder record ref for this file          RecordRef folderRef =
