Hi, If I open the two document libraries (which are in seperate site collections but under the same web application) http://projects/sites/siteaA/Documents and http://projects/sites/siteB/Documents in explorer view and try to drag a document from A > B or B < A I get the following error "Cannot move <File Name> Cannot read from the source file or disk." If I open two document libraries in explorere view that are under different site collections and web applicaions but in the same farm e.g. http://projects/sites/siteaA/Documents and http://departments/sites/anothersite/Documents and drag a document between them it works fine!! Can anyone see if they have the same issue? My farm is running on Server 2008 Rel 2 and is patched to version 12.0.0.6504 Thanks Dave

Hi Dave, This is a by design behavior that the design of SharePoint source code doesn't authorize to do a MOVE between sites collections under the same web application. In different web application circumstance, it works as it use PUT WebDAV method when moving files, also SharePoint proc_RenameUrl store pro is not used. However, when moving files between site collections under the same web application via Explorer View in Windows 7 and Vista, it tries a MOVE instead of a PUT verb. It use proc_RenameUrl which is not designed to be used between sites collections. Windows XP should work in this scenario though. A workaround is to copy files to the target location and then delete the items in the source. Thanks & Regards. Lily Wu

Hi David Cornall, There is a White Paper released by Microsoft to troubleshoot SharePoint Explorer View Problem. Please refer to the link below. I hope this document will help you out. http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=c523ac7a-5724-48be-b973-641e805588f4 With Best Regards, Muhammad Tariq Khan.

Hi, Muhammad thanks for the white paper I will have a read of it. Lilly as you suggest performing a copy and paste works fine. A bit annoying that this is "by design" rather than a bug however at least you have given me a good workaround, well at least until we move to windows 7!!!! Thanks Dave
