This is my rather simple take on creating a Discord Media Downloader.
Download the latest Version from the Releases section in this repository, then simply run it and answer the questions it asks you, after that it should automatically download all the Videos/Images from the Channel you have selected.
You will need .Net 5 for this, so make sure you have the runtime installed. Since I am using external dependencies for, for example Json, I personally suggest Publishing the Program to a Folder and make it a single-executable application.
This Program will use your Discord Token and create a Self-Bot! This IS against ToS, I do NOT take responsibility for any damaged caused by people using my Software!
