What is a .!BT file?

The file extension .!BT is associated with a BitTorrent Incomplete Download File. This means it is a file that has not been fully downloaded yet. It is created by BitTorrent, which is a program used to download files through a method called torrenting. Torrenting allows you to download large files by connecting with many other computers that already have the file, and downloading bits of it from each of them.

When you are downloading a file using BitTorrent, and you have chosen the option "Append .!bt to incomplete files" in the BitTorrent settings, any file that is still in the process of downloading will have .!BT at the end of its name. This helps you to easily see which files have not finished downloading yet.

The programs that can open these .!BT files are BitTorrent Classic and other versions of BitTorrent designed for Windows computers. Once the download is complete, BitTorrent automatically removes the ".!bt" part from the file's name, changing it back to its original file extension. This indicates that the file is no longer incomplete and is ready to be used.

Remember, .!BT files are specific to the Windows version of BitTorrent, so if you are using a different operating system, you might not see this kind of file.
