procedure FileRename(AHandle:THandle;FromName,ToName:string);
var
  SHFileOpStruct:TSHFileOpStruct;
begin
  with SHFileOpStruct do
  begin
    Wnd:=AHandle;

Answer 2

程序没错，但是注意：
1、要uses ShellAPI
2、FromName,ToName要传送全名，如：
FileRename(handle,'g:\档.txt','g:\档11.txt');
或者
FileRename(0,'g:\档.txt','g:\档11.txt');—————————————————————————————————
宠辱不惊，看庭前花开花落，去留无意；毁誉由人，望天上云卷云舒，聚散任风。
