The TREC format was developed in the 1990s by the National Institute of Standards and Technology (NIST) to facilitate the evaluation of search engines and information retrieval systems. The format is used to store the results of a search query, including the ranking of documents, relevance judgments, and other metadata.
Most standard media players (like Windows Media Player, QuickTime, or VLC) cannot play TREC files directly because they require the specific TechSmith codec to interpret the raw screen data and cursor information. .trec file extension
