What are !BT files and how to open them

Are you having problems opening a !BT file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a !BT file?

A .!BT file is a BitTorrent partial downloaded file.

Files that contain the .!bt file extension are normally assigned to partially-completed BitTorrent downloads. BitTorrent is a P2P (peer-to-peer) online file-sharing protocol that allows users to share files online. It is popular for the sharing of movies, music, and software files.

When a BitTorrent download is in progress it is given the .!bt file extension until the download has completed. Once the download is complete it is given the proper file extension.

For example, if an MP3 music file is being downloaded using the BitTorrent client, the file would be saved with the name of filename.!bt during the download process. Once the download had been completed, the file would be renamed with the proper filename.mp3 file suffix.
