When you use Windows Explorer to connect to a shared folder on a remote computer on your network, and you double-click a file in that shared folder to open it, it may take a longer time than expected to open the file. For example, you may experience this issue when you open a Microsoft Office document over a slow connection, such as a 64-kilobits-per-second (kbps) Integrated Services Digital Network (ISDN) connection on a wide area network (WAN).
This issue occurs because Windows Explorer tries to obtain detailed information about the remote share and about the file that you are opening. This operation may take a long time over a slow connection.
