The IS file extension is associated with the Modula-3 programming language that has been used in research circles. it has not been adopted widely in industry. The .is file stores intermediate assembly data.

Modula-3 was designed by Luca Cardelli, Jim Donahue, Mick Jordan, Bill Kalsow and Greg Nelson at the Digital Equipment Corporation (DEC) Systems Research Center (SRC) and Olivetti in the late 1980s.

Help how to open IS files:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert file with extension IS:

As far as we know, this .is file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
