Please pay attention:
Only files having internal version resource can be compared!
As known, Windows supports version information for such file types as DLL, EXE, OCX, TTF, FON and some others. VerMap does not compare version of files without such version resource, e.g. text files (TXT), Winword documents (DOC, RTF), image files (BMP, GIF, JPG), wave sounds (*.WAV) and many other formats.
In order to compare files in two folders based on size, date and binary difference you should use some other application (e.g. FileSync of FileWare).
