.DA2 File Extension

A DA2 file is a data file created by HammerTap DeepAnalysis, a program used to research eBay auctions. It contains a list of auction results, buyer and seller information, and other sales data. Sellers use DA2 files to analyze sales data and generate reports.

HammerTap DeepAnalysis, which was renamed to just HammerTap, was an eBay market research tool that sellers used to gather and analyze sales activity for various items and categories of items. After using DeepAnalysis to retrieve data, sellers could save that data as a DA2 file, so they could load and review the data again in the future.

You can open a DA2 file with HammerTap (formerly known as HammerTap DeepAnalysis). HammerTap is no longer available for purchase, so if you do not already have HammerTap installed, you may not be able to open your DA2 file.

A DA2 file may also be a license file used by some versions of Lavasoft Adaware, an antivirus program. It contains information used to activate a user's purchased copy of Adaware. Current versions of Adaware do not use DA2 files.

In previous versions of Adaware, users could use the registration information a DA2 file contained to activate their copy of the software. Now, users must sign in with their Adaware account credentials (typically an email and password) to activate the program.

NOTE: Adaware was previously known as Ad-Aware.

For instructions on how to use a DA2 file with Lavasoft Adaware, refer to the documentation you received with your license file. Remember, current versions of Adaware do not use DA2 files, and instead require you to log in to your Adaware account.

An AGT file is a game data file referenced by AGiliTy, an Adventure Game Toolkit (AGT) interpreter. It contains encrypted game data about rooms featured in the game, including descriptions of rooms and help messages. AGT games reference AGT files as a player navigates through a story.

In order to navigate through Interactive fiction games, like AGT games, you must type commands in the game. The story will change depending on what decisions you type.

AGT games are often packaged with many files. Each file contains game data, including .VOC, .TTL, and .INS 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 clutter, load time, and game size.

NOTE: DA2 files are similar to .DA1, .DA3, and .DA4 files. These files contain game data referenced for different aspects of the game.

AGT files are not meant to be opened. AGiliTy references and loads AGT files as needed as a player plays a game.

You can use the AGT2AGX utility included with AGiliTy to package several AGT files as a single AGX file.
