The 2DK file extension identifies data saved in the OS/2 SKF format. The file belongs to the OS/2 software environment rather than to a common, application-independent interchange format.
IBM OS/2 is a legacy operating system. eComStation, developed by Serenity Systems, was a later OS/2-derived operating system and was not simply a renamed version of IBM OS/2. The 2DK format is consequently uncommon on current systems.
Open a 2DK file in an OS/2 installation or compatible OS/2 environment that supports the SKF format.
If the file can be opened in OS/2, conversion or export must be performed by software that can read the SKF format.
