KEA! X was developed by KEA Systems as a PC X server. It integrated the X Window System environment with the Microsoft Windows desktop and allowed Windows users to run X client applications.
An XSF file stores the information required by KEA! X to start an X client. It is a support file for the software rather than a general-purpose document, and is used as part of the program's client-starting workflow.
KEA Systems was acquired by Attachmate Corporation, and KEA! X appears to have been discontinued. XSF files are therefore mainly relevant to older installations of the software.
Open an XSF file with KEA! X on Microsoft Windows. The file is intended to be used by the program's client-starter feature rather than opened as a standalone document.
If KEA! X is not installed, a current general-purpose application is unlikely to open the file correctly.
There is no widely supported conversion format for KEA! X client starter files. An XSF file can normally be used only with KEA! X.
If the required X client is still available, recreate its launch settings in another X server or launcher rather than converting the XSF file directly.
