How can we check if a file Exists or not using Win32 program?

Question

How can we check if a file Exists or not using a Win32 program? I am working for a Windows Mobile App.

You can call FindFirstFile.

Here is a sample I just knocked up:

#include 
#include 
#include 

int fileExists(TCHAR * file)
{
   WIN32_FIND_DATA FindFileData;
   HANDLE handle = FindFirstFile(file, &FindFileData) ;
   int found = handle != INVALID_HANDLE_VALUE;
   if(found) 
   {
       //FindClose(&handle); this will crash
       FindClose(handle);
   }
   return found;
}

void _tmain(int argc, TCHAR *argv[])
{
   if( argc != 2 )
   {
      _tprintf(TEXT("Usage: %s [target_file]\n"), argv[0]);
      return;
   }

   _tprintf (TEXT("Looking for file is %s\n"), argv[1]);

   if (fileExists(argv[1])) 
   {
      _tprintf (TEXT("File %s exists\n"), argv[1]);
   } 
   else 
   {
      _tprintf (TEXT("File %s doesn't exist\n"), argv[1]);
   }
}
