MORE INFORMATION

When you copy a file to a WebDAV server by using the Windows XP WebClient, this process involves two internal steps:

WebClient copies an empty file (0 bytes) and then sets the file attributes.
WebClient copies the file contents and then sets the file attributes.

Notes

If you copy an empty file to a WebDAV server, WebClient performs only step 1. Therefore, the time stamp is correct in this situation.
The Microsoft Data Access Internet Publishing Provider DAV client does not support DAV attributes.
