Yes, there is:

    HANDLE hFile = FindFirstFile("*.exe", &fdFindFileData);

To do it recursively, however, you would need two separate searches - *.exe 
to find just files in a single folder, and then *.* to find subfolders for 
recursion.  It is easier to just use *.* by itself and then filter the 
results as needed.

Sure, it does:

    void __fastcall ScanForApps(const AnsiString &Folder, TStrings *Matches)
    {
        AnsiString tmpFolder = IncludeTrailingBackslash(Folder);
        WIN32_FIND_DATA fd = {0};

        HANDLE hFile = FindFirstFile( (tmpFolder + "*.*").c_str(), &fd);
        if( hFile != INVALID_HANDLE_ VALUE )
        {
            do
            {
                if( fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY )
                    ScanForApps(tmpFolder + fd.cFileName, Matches);

                else if( AnsiSameText(ExtractFileExt(fd.cFileName), 
".exe") )
                    Matches->Add(tmpFolder + fd.cFileName);
            }
            while( FindNextFile(hFile, &fd) );
            FindClose(hFile);
        }
    }

Open each file and analyze its contents to see if a PE (Portable Executable) 
header is present.

It looks at the file attributes, which you are not doing yet.

The extension on such a file is ".txt", not ".exe" or ".exe.txt".  A file's 
extension begins at the last "." in the name.
