Synergy/DE, from Synergex, is a development environment for creating applications with the Synergy DBL programming language. Its data management features use indexed files for storing and retrieving application data.
An ism file contains index information created by Synergy/DE. It is a software-specific support file that works with the associated Synergy/DE data rather than serving as a general-purpose interchange format. The format is used by Synergy/DE software on Microsoft Windows.
An ism file is normally opened automatically by the Synergy/DE application or by a Synergy/DE program that uses the indexed data. It is not intended to be read as a text document or opened independently in a general-purpose file viewer.
On Microsoft Windows, install the compatible Synergy/DE environment and open the associated data through the application that created it. Avoid editing the file directly, because changing an index outside Synergy/DE can make it unusable.
An ism file is an index rather than a document or interchange file, so it normally has no useful standalone conversion. Synergy/DE applications or their data-management tools may be able to rebuild the index from the associated data when moving or maintaining a database.
