Cardfile is a personal information manager that was distributed with Microsoft Windows starting from the original version 1.01 until Windows NT 4.0 Server. Cardfile is also included with Windows 98 and Windows Millennium Edition, but has to be installed manually from the installation CD-ROM. Beginning with Windows 3.1, Cardfile supported Object Linking and Embedding. The version supplied with Windows NT versions was a 32-bit application with unicode support. Both later versions could read .crd files created by previous versions.
A 64-bit version is available at http://www.geert.com/CardFile.htm (April 27 2014) that runs on Windows 8 and possibly other 64-bit Windows OS. The MGC signature of .crd files is the initials of the author, Mark Cliggett.
Cardfile's source code was delivered with the Windows SDK. The availability of the source code was apparently not known to everybody, because one can find a 1989 reverse engineering of the (very simple) file format on the Internet.
Localized versions of Windows may have contained Cardfile under other names, for example repert.exe (Répertoire) for the French language Windows.
Schedule+, which appeared with Windows 95, and Outlook Express, which appeared with Windows 98, have built-in contact managers which can replace Cardfile. Schedule+ had the ability to import Cardfile .crd files through its Import/Export Add-on pack.

Running under later Windows versions
The 16-bit version of Cardfile (File Version 126.96.36.199) can run on all x86-based 32-bit versions of Windows including Windows 7 32-bit. Cardfile.exe ver. 188.8.131.52 was included on the Windows 98 and Windows Millennium Edition installation CD but was not installed by default. In 64-bit Windows 7 the Cardfile 32-bit version 3.51 has to be used. It supports long file names and unicode characters.
