The MoveFileEx function moves an existing file or directory.

The MoveFileWithProgress function is equivalent to the MoveFileEx function, except that MoveFileWithProgress allows you to provide a callback function that receives progress notifications.

BOOL MoveFileEx(  LPCTSTR lpExistingFileName,  LPCTSTR lpNewFileName,  DWORD dwFlags);
Parameters
lpExistingFileName
[in] Pointer to a null-terminated string that names an existing file or directory on the local computer.
If dwFlags specifies MOVEFILE_DELAY_UNTIL_REBOOT, the file cannot exist on a remote share because delayed operations are performed before the network is available.

In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see Naming a File

Windows 2000:  If you prepend the filename with "\\?", you cannot also specify the MOVEFILE_DELAY_UNTIL_REBOOT flag for dwFlags.
lpNewFileName
[in] Pointer to a null-terminated string that specifies the new name of lpExistingFileName on the local computer.
When moving a file, the destination can be on a different file system or volume. If the destination is on another drive, you must set the MOVEFILE_COPY_ALLOWED flag in dwFlags.

When moving a directory, the destination must be on the same drive.

If dwFlags specifies MOVEFILE_DELAY_UNTIL_REBOOT and lpNewFileName is NULL, MoveFileEx registers the lpExistingFileName file to be deleted when the system restarts. If lpExistingFileName refers to a directory, the system removes the directory at restart only if the directory is empty.

dwFlags
[in] This parameter can be one or more of the following values.
