Cardfile is an application of Microsoft Windows for creating index cards (stored in the .CRD file format).

History[edit | edit source]

Cardfile was first introduced in the Windows 1.0 Beta Release and initially released in the Windows 1.01 retail release.

Up until Windows 2.x, the file extension with which cards are saved depends on the system locale. Since Windows 3.0, all locales apart from the English one use the .CRD file extension.

Windows NT 4.0 is the last version to have Cardfile. The app is no longer present in clean installations as of Windows 95, though it will remain when upgrading from an earlier Windows version. The Windows 3.1 version of Cardfile is also included on the installation media of Windows 98 and Windows Me.
