The k01 file extension is associated with Clarion, a Windows development environment from SoftVelocity used to create business and database applications.
A k01 file contains database key data used with a Clarion database. It is normally one component of a database file set rather than a complete database that can be used on its own.
The K01 format is associated primarily with older versions of Clarion and the databases created with them.
Use Clarion on Microsoft Windows to work with a k01 file. The file is normally opened or used together with its associated Clarion database files, rather than as a standalone document.
A k01 file is an auxiliary database key file and cannot usually be converted meaningfully on its own. Keep it with the related Clarion database files.
To move the data to another database format, open the associated database in Clarion and export or migrate the database contents using the available database tools.
