Model file created by TAK (Thermal Analysis Kit) 2000, an engineering application used for analyzing the thermal characteristics of thermal systems; saves parameters for a thermal model, including nodes, conductors, and heat sources; used for generating output such as temperatures, heater statuses, and heat source information.

TAK files are created in an ASCII text format. They are authored using a text editor and then run in TAK 2000.

Audio file created in the Tom's lossless Audio Kompressor (TAK) format; uses an adaptive linear forward prediction technique to reduce the size of an audio file without losing audio quality; also supports non-audio data such as CD cover images or cue sheets.

The TAK method of compression and decompression aims to provide higher compression ratios than other techniques while performing faster than other lossless compressors in benchmarks. The TAK format can be played back using plugins for Winamp and Foobar2000. TAK files can be compressed and decompressed using Tak, a program provided on the TAK development page. The downloaded package also includes the Winamp plugin and the TAK SDK. NOTE: The TAK homepage is written in German.
