The tree diagram of the multi-file Torrent structure is:
Multi-file Torrent
├─announce: The main server of the Tracker
├─announce-list: List of Tracker server
├─comment: The comment of the seed file
├─comment.utf-8: The utf-8 encoding of the seed file comment
├─creation date: The time when the seed file was created, which is the number of seconds from January 1, 197, 00:00:00 to now.
├─encoding: The default encoding of the seed file, such as GB2312, Big5, utf-8, etc.
├─info: All information about the download file
│ ├─files: Indicates the name of the file
│ │ ├─length: The size of the file (Byte)
│ │ ├─path: The name of the file, which cannot be changed when downloading
│ │ └─path.utf-8: The UTF-8 encoding of the file name, same as above
│ ├─name: The recommended folder name, which can be changed when downloading
│ ├─name.utf-8: The UTF-8 encoding of the recommended folder name, same as above
│ ├─piece length: The size of each file block (Byte)
│ ├─pieces: The characteristic information of the file (all files are divided into blocks of piece length bytes, each block calculates a SHA1 value, and then these values are connected to form)
│ ├─publisher: The name of the file publisher
│ ├─publisher-url: The website of the file publisher
│ ├─publisher-url.utf-8: The utf-8 encoding of the file publisher's website, same as above
│ └─publisher.utf-8: The utf-8 encoding of the file publisher's name
└─nodes: This field contains a list of IPs and corresponding ports, which are used to connect the initial node of DHT
The tree diagram of the single-file Torrent structure is:
(The meaning of each field is the same as the multi-file Torrent, except that the single-file Torrent does not have the files field)

In addition, it should be noted that the format of the magnet link converted from the parsed BT seed file is: magnet:?xt=urn:btih: + hash value
