Hello,
Sharepoint has limited ways to bulk movement (in-out) of documents.
Either you can use the explorer view or you can use "Open with Windows Explorer" option directly from document library. You can also map the document library as network folder/shared drive on your workstation, and then bulk copy/paste the documents.
Alternatively you may also use the sharepoint web services to copy-paste the documents.
Hope this helps,
-Regards, Rohan Chittyal --------------------------------------------------------------
