Instruction file used by AGiliTY, an Adventure Game Toolkit (AGT) interpreter; contains instructions on how to play the AGT game it is packaged with; does not need to be included with AGT game.

An AGT game is played by typing commands to navigate through a story. It's similar to a choose-your-own-adventure book. AGiliTy emulates older machines from the 1980s and 1990s that played the original AGT games. AGT games can be packaged with a wide variety of files that contain game data, including .TTL and .VOC files. Because of the large number of files that accompany the AGT game, the files can be converted into a single .AGX file with the AGT2AGX utility that comes with AGiliTy. This conversion reduces load time, game file size, and clutter.

Format used to store instrument samples used by Ensoniq synthesizers and sound cards.

Data file created by Inspiration, a visual thinking and learning program typically used for educational purposes; sometimes referred to as a "mind map" file, since it may contain concept maps, webs, and idea maps.

Inspiration files can be viewed visually in Diagram View or displayed in a linear format, using Outline View.

Locates IP addresses and names of computers on the Internet, often referred to as "name resolution;" translates the IP address into a name that is stored by the Windows Internet Naming Service; not meant to be manually opened or altered.

File used by Windows for setting up dial-up and broadband Internet connections; contains connection setup information that enables Windows to setup Internet access with an ISP when opened; also commonly used for setting up Internet Explorer (IE) LAN connection settings.

System administrators and ISPs sometimes provide IE connection settings files to users with a URL to the INS file. However, as a security precaution, webpage links to INS files are blocked by Internet Explorer so that arbitrary scripts cannot be run on the local computer from a Web link. Instead of placing the link in the Web address field, you need to use the the IE settings dialog to apply the connection settings.

An INS file is an installer script used by LaTeX typesetting software. It is typically distributed with a .DTX DOCTex package and contains instructions for extracting the DTX content into separate files, such as .STY or .TEX files.

INS and DTX files are typically packaged together in a .ZIP archive. To run an INS file, first, extract the files from the ZIP archive using a Zip-decompression utility. Then, open the INS file in a LaTeX application or type latex filename.ins at the command line if the LaTeX command-line utilities are installed.

Contains one instrument definition and references to external audio files used by the instrument; used by both Mac and Windows platforms, but incompatible with each other.

Does not contain actual audio data.
