What is the .CRD File Extension?

.CRD File Extension Description:

Cardfile was a program developed by the Microsoft Corporation. The program is a personal information management (PIM) program. The program is used to store and manage information in an index card format. Microsoft created the program and it was included in the early versions of the Microsoft Windows operating system. The Cardfile software uses the CRD file extension as the default extension of the projects it creates.

Cardfile can store several kinds of data with the .crd file extension. The application can then search, sort and manage information stored in files with the CRD file extension. The Cardfile software is no longer distributed or supported by Microsoft. There are several other card programs that can open files with the file extension CRD. Cardfile was no longer included in later versions of the Windows platform, such as Windows 95 and later. Other Microsoft programs cannot open files with the .crd file extension. The Microsoft Corporation developed file format converters that allow users to convert Cardfile data into other formats.

Programs like the AZZ Cardfile can also open and edit files with the CRD file extension. The program has similar functions to Microsoft's Cardfile. AZZ Cardfile creates and stores files with the .crd file extension. Cardfiles are given the CRD file extension so that other Card management programs can open them. Support for files with the file extension .crd is also built into other card management programs. This is because the Cardfile program was one of the earlier applications with this function.

Text files that contain guitar tabs also use the CRD file extension. Guitar tabs are annotated song lyrics that give guitar players instructions on how to play melody on a guitar. Files with the .crd file extension contain plain ASCII text characters. They can be opened and edited by any text editor. Guitar players can use files with the .crd file extension to refer the note, strumming and chords to be used in specific parts of a song.

Another program that uses the CRD file extension is Spanish Whiz from GB Blanchard. The software is an educational game created by the company to teach people the Spanish language. Sound files for the game are stored with the CRD file extension. Files stored with the file extension .crd contain pronunciation of Spanish words and phrases.
