请帮忙找个API

[sqsavagepointer]

我想实现一个这样的功能，在一个文件夹中获得所以文件的文件名，然后把那些文件作些复制、删除等操作，要用到的关键API是什么呢？如果能给出个源程序框架，那就更好了，谢谢！

WIN32_FIND_DATA FileData;
HANDLE hSearch;
DWORD dwAttrs;
char szDirPath[] = "c:\\TEXTRO\\";
char szNewPath[MAX_PATH];
char szHome[MAX_PATH];

BOOL fFinished = FALSE;

// Create a new directory.

if (!CreateDirectory(szDirPath, NULL))
{
ErrorHandler("Couldn't create new directory.");
}

// Start searching for .TXT files in the current directory.

hSearch = FindFirstFile("*.txt", &FileData);
if (hSearch == INVALID_HANDLE_VALUE)
{
ErrorHandler("No .TXT files found.");
}

// Copy each .TXT file to the new directory
// and change it to read only, if not already.

while (!fFinished)
{
lstrcpy(szNewPath, szDirPath);
lstrcat(szNewPath, FileData.cFileName);
if (CopyFile(FileData.cFileName, szNewPath, FALSE))
{
dwAttrs = GetFileAttributes(FileData.cFileName);
if (!(dwAttrs & FILE_ATTRIBUTE_READONLY))
{
SetFileAttributes(szNewPath,
dwAttrs | FILE_ATTRIBUTE_READONLY);
}
}
else
{
ErrorHandler("Couldn't copy file.");
}

if (!FindNextFile(hSearch, &FileData))
{
if (GetLastError() == ERROR_NO_MORE_FILES)
{
MessageBox(hwnd, "No more .TXT files.",
"Search completed.", MB_OK);
fFinished = TRUE;
}
else
{
ErrorHandler("Couldn't find next file.");
}
}
}

// Close the search handle.

if (!FindClose(hSearch))
{
ErrorHandler("Couldn't close search handle.");
}

[arvid_gs]

CloseHandle(hFile);
DeleteFile("MYFILE.TXT");

FindFirstFile(Ex)
FindNextFile
FindClose
CopyFile(Ex)
DeleteFile
这些就差不多了。
