With this lib you can upload/download theoretically infinite content on Telegram Servers.

This works by uploading/downloading files like a normal bot would, so we have the same limitations that Bots have, For example the maximum size of files we can download is 20mb, so we just need to splice them before uploading to get around this limitation

you just need to create a bot on BotFather, and get the Token like 1234567890:AAHqadAckv5dMLS47rKsTYD2u_zISsiIBrU

Then you need to start the bot by sending him a message

And you need to know your Telegram ID so the bot knows in which chat Upload the files. you can get your account ID by sending a message to chatIDrobot. You will get something like this 1470338630

Upload:

$ java -jar TelegramStorage.jar upload /Path/To/File

output: file.ext.zip uploaded as id: BQACAgEAAxkDAAP_YTeBrJ5Z9D1OXWw1ZyZBV_C-Zg0AAgsCAALMV8BFkYmTAniEJ3IgBA

Note: ID will be longer for bigger files

Download:

$ java -jar TelegramStorage.jar Download *IDHERE* | OPTIONAL | /Path/To/Ouput/Dir/
