Answer 1

You can get the SPFile object and then write it using FileStream. Below is the code snippet -

SPFile file = web.GetFolder("Documents").Files[fileName];
//SPFile file = item.ParentList.ParentWeb.GetFile(item.Attachments.UrlPrefix +  fileName); ... get attachments
FileStream outStream = new FileStream(localFileName, FileMode.Create);
byte[] fileData = file.OpenBinary(); 
outStream.Write(fileData, 0, fileData.Count()); 
outStream.Close(); 

fileName - name of file in document library.

"Documents" - name of the document lib

localFileName - file name on the local drive

It seems my article http://sharepointdragons.com/2011/10/07/parallel-programming-in-sharepoint-2010-the-back-to-the-future-pattern/ does exactly what you need. You need to leverage the Task Parallel Library (TPL) to accomplish this. Read the article and do something like it. You have one advantage, as you're only downloading stuff, you won't need to use .NET 3.5 (to call the SharePoint object model) and wrap it in .NET 4 code like I needed to do in the article.

Here is the complete code -

SPDocumentLibrary docLib = (SPDocumentLibrary)web.Lists.TryGetList(DOC_LIB);
SPFolderCollection folderColl = docLib.RootFolder.SubFolders;
IEnumerator folders = folderColl.GetEnumerator();
while (folders.MoveNext() != false)
{
	folder = (SPFolder)folders.Current;
	SPFileCollection fileColl = folder.Files;
        IEnumerator files = fileColl.GetEnumerator();
        while (files.MoveNext() != false)
        {
              SPFile file = (SPFile)files.Current;
	      FileStream outStream = new FileStream(localFileName, FileMode.Create);
	      byte[] fileData = file.OpenBinary(); 
              outStream.Write(fileData, 0, fileData.Count()); 
              outStream.Close();  
        }
}

Hope this helps.
