    DownloadBot

    DownloadBot

    A distributed cross-platform Telegram Bot

    A distributed cross-platform Telegram Bot that can control your Aria2 server, control server files and also upload to OneDrive / Google Drive. This project is mainly to use a small hard disk server for offline downloading, for large BitTorrent files to be downloaded in sections according to the size of the hard disk, each time downloading a part, then uploading the network disk, deleting and then downloading the other parts, until all the files are downloaded. At the same time, communication via the bot protocol facilitates use on machines that cannot intranet penetration and simplifies the usual use of download programs for added convenience. For links, sending a message directly to the Bot will directly identify and download them. It can actually delete files from the download folder, which is not possible with web panels such as AriaNG, and is very convenient as a tool for managing downloads and notifying timely completion of downloads.
