What is a BTSEARCH file? A BTSEARCH file is a search engine definition file used by BitTorrent applications, such as BitTorrent and uTorrent. It is saved in an XML format and contains search engine information that can be added to a BitTorrent application user interface. BTSEARCH files also include the name, description, and URL of each search engine.

More Information Once a BTSEARCH file has been imported into BitTorrent or uTorrent, you can select the added search engine from the search box on the user interface. Additionally, you can view the installed search engines by selecting Options → Preferences → Advanced → UI Extras . NOTE: The BTSEARCH format is based on the OpenSearch description document, but only supports a subset of the specification. The Mac version of uTorrent does not support BTSEARCH files.
