Search a file in a directory - c++

Question

I work in a project and I need to know if a file is unique in a directory or not.
So how can I find if a file exists in a directory or not?
I have the file name without extension and the path of the directory.

Answer 1

There's no ready-made function for this I think, but you can use something like this:
static bool fileExists( const char *path )
{
const DWORD attr = ::GetFileAttributesA( path );
return attr != INVALID_FILE_ATTRIBUTES &&
( ( attr & FILE_ATTRIBUTE_ARCHIVE ) || ( attr & FILE_ATTRIBUTE_NORMAL ) );
}
This verifies that it's a "normal" file. You might want to add/remove flag checks if you want to deal with hidden files, too.

Answer 2

I prefer to do this on a C++ way, but you mentioned a Visual-C++ tag, so there's a way to do it on Visual-C++.NET:
using <mscorlib.dll>
using namespace System;
using namespace System::IO;
bool search(String folderPath, String fileName) {
String* files[] = Directory::GetFiles(folderPath, fileName+".*"); //search the file with the name fileName with any extension (remember, * is a wildcard)
if(files->getLength() > 0)
return true; //there are one or more files with this name in this folder
else
return false; //there arent any file with this name in this folder
}
