        if (CFile::GetStatus(filename, status))

10x, Roger

also FindFirstFile

sorry for sore dull ques...

This question has been asked countless times. You should do a search before posting question.

[tigrushke]

You can also check for a file existance or a folder existence like that:

HANDLE hFind = INVALID_HANDLE_VALUE;
WIN32_FIND_DATA fileFound;

// Search for the specified file
hFind = FindFirstFile(filePath, &fileFound);

// if file to be copied exists
if (!(hFind == INVALID_HANDLE_VALUE))
{
// Do something here
}

I hope it helps!
Poka!

I prefer to use GetFileAttributes to check the existence of a file.
And cilu's absolutely correct: you should always search CG and Google well before you post.

CString szPath("c:\\windows");
CString szFile("c:\\test.txt");

DWORD dwAttr = GetFileAttributes(szPath);
if(dwAttr == 0xffffffff)
{
  DWORD dwError = GetLastError();
  if(dwError == ERROR_FILE_NOT_FOUND)
  {
    // file not found
  }
  else if(dwError == ERROR_PATH_NOT_FOUND)
  {
    // path not found
  }
  else if(dwError == ERROR_ACCESS_DENIED)
  {
    // file or directory exists, but access is denied
  }
  else
  {
    // some other error has occured
  }
}
else
{
  if(dwAttr & FILE_ATTRIBUTE_DIRECTORY)
  {
    // this is a directory
    if(dwAttr & FILE_ATTRIBUTE_ARCHIVE)
      // Directory is archive file
    if(dwAttr & FILE_ATTRIBUTE_COMPRESSED)
      // Directory is compressed
    if(dwAttr & FILE_ATTRIBUTE_ENCRYPTED)
