Searching recursive(with code)

I needed to search for a single file, in a particular directory. Although there are plenty of examples, most examples are pretty big to just find a file. So i decided to make my own. Im posting it since i am not shure if this done the right way. Would this work an all win versions? For every user?? If its correct, i hope other might be able to use it.

Code:

// searches recursive for fileName in dir and if fileName is found, the fullpath is copied into fileName
bool SearchFile(char dir[FILENAMESIZE],char fileName[FILENAMESIZE])
{
	WIN32_FIND_DATA fd;
	char txt[FILENAMESIZE];
	sprintf(txt,"%s%s",dir,fileName);
	HANDLE hFind = FindFirstFile(txt,&fd);
	FindClose(hFind);
	if(hFind != INVALID_HANDLE_VALUE)
	{
		sprintf(fileName,"%s%s",dir,fd.cFileName);
		return true;
	}
	sprintf(txt,"%s*",dir);
	hFind = FindFirstFile(txt,&fd);
	while(FindNextFile(hFind,&fd))
	{
		if((fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) && strcmp(fd.cFileName,"..") != 0)
		{
			sprintf(txt,"%s%s\\",dir,fd.cFileName);
			if(SearchFile(txt,fileName))
			{
				FindClose(hFind);
				return true;
			}
		}
	}
	FindClose(hFind);
	return false;
}

you use it like this:

Code:

void FindSomeFile()
{
    char dir[FILENAMESIZE];
    char fileName[FILENAMESIZE];
    strcpy(dir,"C:\\");
    strcpy(fileName,"p*.exe");
    if(SearchFile(dir,fileName))
    {showMsg(fileName);}
    else
    {}
}
