What is the .DYN File Extension?

.DYN File Extension Description:

The DYN file extension is used to store information generated by the Lotus 1-2-3 program. Lotus Software developed the program. IBM eventually purchased Lotus and absorbed it as a division for software development. Lotus 1-2-3 was originally developed for systems running on DOS. The program was later ported to other operating systems.

Lotus 1-2-3 is primarily a spreadsheet program. However, the "1-2-3" part of its name was included to denote its two other functions. Aside from creating and maneuvering spreadsheets, the program can also create charts and graphs, and manage and create databases.

Files created with the DYN file extension contain projects from Lotus 1-2-3. The .dyn file extension is often attached to spreadsheets, which contain data, charts and images. The program can also edit, sort and filter data stored with the DYN file extension.

The Lotus 1-2-3 program led to the rise of several spreadsheet programs. The popularity of the program decreased with the rise of the Excel software form Microsoft. There is some conversion software that can convert files with the DYN file extension to other formats. The program is still being distributed as a part of the Lotus SmartSuite. This program suite released by IBM is meant to provide the same support of Microsoft's Office program suite.

Dyno2000 engine simulation programs by Motion Software also use the DYN file extension. The programs created by Motion Software allow users to view the inside of cylinders used by automobile engines. The program to store processes uses files with the DYN file extension.

The Dyno2000 application is compatible with most recent Windows platforms. The program can simulate the actions and mechanics of an engine. The program uses resource files stored with the file extension .dyn to calculate thermodynamic, frictional and fluid-dynamic conditions in engines. The program can show users all of the four-cycle processes undergone by engine cylinders.

Files with the DYN file extension store the processes of the application. Programmers encode certain processes that are used by the program in resource files. These files are called and referenced whenever the software needs to process any functions.
