如何实现文件的COPY命令急！！！

[抱朴守拙]

就是Copy

[blazingfire]

function DoCopyDir(sDirName:String;
sToDirName:String):Boolean;
var
hFindFile:Cardinal;
t,tfile:String;
sCurDir:String[255];
FindFileData:WIN32_FIND_DATA;
begin
//先保存当前目录
sCurDir:=GetCurrentDir;
ChDir(sDirName);
hFindFile:=FindFirstFile('*.*',FindFileData);
if hFindFile< >INVALID_HANDLE_VALUE then
begin
if not DirectoryExists(sToDirName) then
ForceDirectories(sToDirName);
repeat
tfile:=FindFileData.cFileName;
if (tfile='.') or (tfile='..') then
Continue;
if FindFileData.dwFileAttributes=
FILE_ATTRIBUTE_DIRECTORY then
begin
t:=sToDirName+'\'+tfile;
if not DirectoryExists(t) then
ForceDirectories(t);
if sDirName[Length(sDirName)]< >'\' then
DoCopyDir(sDirName+'\'+tfile,t)
else
DoCopyDir(sDirName+tfile,sToDirName+tfile);
end
else
begin
t:=sToDirName+'\'+tFile;
CopyFile(PChar(tfile),PChar(t),True);
end;
until FindNextFile(hFindFile,FindFileData)=false;
FindClose(hFindFile);
end
else
begin
ChDir(sCurDir);
result:=false;
exit;
end;
//回到原来的目录下
ChDir(sCurDir);
result:=true;
end;

以上是文件及文件夹Copy

[jinjintalk]

copyfile(pchar(d:\待复制文件),pchar(savedialog1.filename)，false)

再给一个用ShellAPI的方法
uses
ShellAPI;

function DelPath(const Handle: THandle; const SrcFile, DstFile: String): Boolean;
var
SHFileOpStruct: TSHFileOpStruct;
begin
if FileExists(SrcFile) or DirectoryExists(SrcFile) then
begin
FillChar(SHFileOpStruct, SizeOf(SHFileOpStruct), 0);
SHFileOpStruct.Wnd := Handle;
SHFileOpStruct.wFunc := FO_COPY;
SHFileOpStruct.fFlags := FOF_NOCONFIRMATION;
SHFileOpStruct.pFrom := PAnsiChar(SrcFile);
SHFileOpStruct.pTo := PAnsiChar(DstFile);
Result := SHFileOperation(SHFileOpStruct) = 0;
end
else
Result := False;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
if DelPath(Self.Handle, 'D:\1', 'D:\2') then
ShowMessage('Copy成功！')
else
ShowMessage('Copy失败！')
end;

用COPYFILE就可以了
copyfile(pchar('原文件路径),pchar('目标文件路径'),false);

[qizhanfeng]

copyfile拷贝文件
SHFileOperation文件夹拷贝
上面有不错的例子
