I'm getting the following error when attempting to move a large file (~>50mb)
to a parent folder within a document library using Explorer View:

Unable to move http://<server>/<site>/<doclib>/<folder>/<file>. The file
cannot be accessed. The file may not exist or may be in use or the web server
is temporarily busy.

SharePoint logs the action as follows:

3/9/10 4:36 PM w3wp.exe (0x18CC) 0x1080 Windows
SharePoint Services General 72ng Medium RPC
method = url to web url
3/9/10 4:36 PM w3wp.exe (0x18CC) 0x0838 Windows
SharePoint Services General 72ng Medium RPC
method = move document
3/9/10 4:36 PM w3wp.exe (0x18CC) 0x0838 Windows
SharePoint Services General 72n4 Medium rename
URL = Videos/Uploads/test.mpg
3/9/10 4:36 PM w3wp.exe (0x18CC) 0x0838 Windows
SharePoint Services General 72n5 Medium rename to
newUrl = Videos/test.mpg

The error does not occur for files less than 50mb or if the file is copied
instead of moved from the Uploads sub-folder to its parent Videos document
library.

Any help is appreciated, thanks!

Try adding the site as a map drive or copy the site url from the
address bar and then open the site as a web folder. Check if you are
able to move the file.
If you are using IE8 web folder wont be available when you click on
file -> open.

Explorer view and web folder from the browser uses webdav in the
backgroup. So we are just using the same technology in the background,
but just trying an alternate route.

Hope this helps.
