What is a DTA file?

DTA files mostly belong to Chain Engineering by IWIS. DTA file type is associated with database files used by IWIS Chain Engineering program developed by IWIS.

  • Main Use: IWIS Chain Engineering is application that is used for performing automobile drive chain calculations. This program uses DTA files to store automobile-related information such as engine torque, chain load, and friction. Using the DTA files, the Chain Engineering application performs calculations to suggest the most suitable drive chain for an automobile based on the required drive capacity. IS.dta and IW.dta are the two common database DTA files associated with IWIS Chain Engineering program, where the former refers to the system database file and the latter refers to the chain database file.
  • Other Uses: DTA file is also with game archive files used by the Sonic Robo Blast 2 (SRB2) game. These DTA files either consist of graphics related information of playable characters or the OGG and MIDI files used for audio playback in the SRB2 game. SRB2 DTA files are found in the game directory. Game modders can use DTA files to modify the physical appearance of game characters and the in-game audio although such modifications can sometimes lead to unexpected issues such as crashing of the game while in play.
