Microsoft QBasic coordinates

File type category:
Source code and script file

Date updated: October 25, 2026

The qcf file extension is associated with coordinate data used to create drawings in QBasic and QuickBASIC. The file contains coordinates used by the BASIC program or graphics workflow.

QBasic was Microsoft's simpler, interpreter-based BASIC integrated development environment and was distributed with MS-DOS version 5.0 and later. It was based on QuickBASIC, Microsoft's separate BASIC programming development environment.

Both programs were designed for MS-DOS. The QCF format is a legacy format used with preserved QBasic or QuickBASIC projects.

How to open qcf file?

Open the qcf file in QBasic or QuickBASIC on MS-DOS. On a modern system, an MS-DOS-compatible environment may be required to run these programs.

The file may need to be used from the BASIC program or project that created it rather than opened as a standalone document.

Conversion to other formats is not possible.
