MORE INFORMATION ================ The Mv.exe tool is a 32-bit version of the POSIX MV tool. Mv.exe has the following syntax: mv [/x [/d]] [ ...] The command-line switches are: /x: Do not save files that are replaced. /d: Delay file move until system reboot. For example, to replace the Url.dll file in the Winnt\System32 folder with the Url.dll file located in the Temp folder at the next reboot without saving the replaced file, type the following line: mv.exe /x /d c:\temp\url.dll c:\winnt\system32\url.dll There are two versions of Mv.exe in the Windows NT Resource Kit, a 32-bit Windows-based version and a Posix version. The correct version to use in this instance, the Windows version, is located on the Windows NT Resource Kit CD-ROM in the \filebat\mv.exe folder.
