Moving files between document libraries in Sharepoint
Moving files between document libraries on different Windows Sharepoint Services sites can be quite cumbersome.
Syntergy has a nice cut / copy / paste add-on that helps users a lot for those one-file moves. Doing batch moves though can be done easier and completely for free. I got the tip from this kb article on how to use web folders.
Open up a Internet Explorer window for the source and target folder. Use File -> Open and paste in the url of the document libraries. Make sure you check the box for "Open as Web Folder".
This lets you browse your WSS sites as web folders and supports drag-and-drop between them. Simple and effective.
