What is a DESCRIPTION file?
A DESCRIPTION file contains the official description of a YouTube video. Youtube-dl creates DESCRIPTION files when a user downloads a video from YouTube.com. DESCRIPTION files are plain text files that can be opened in any text editor.
Youtube-dl is a command-line program that can be used to download videos from YouTube.com. When a user uses youtube-dl to download a video, the program creates an .MP4 or .MKV file that contains the video and several related files. One of the created files is a DESCRIPTION file.
The DESCRIPTION file contains the video's official YouTube description at the time of download. Users often keep DESCRIPTION files on hand so they can remember what content a downloaded video contained. If a user uploads the video to a file hosting website, they may also upload the DESCRIPTION file to provide context for the video. For example, youtube-dl users who upload videos to the Internet Archive usually upload DESCRIPTION files alongside videos.
NOTE:Tubeup.py, which uses youtube-dl to download YouTube videos and automatically upload them to the Internet Archive, also creates DESCRIPTION files.
How to open a DESCRIPTION file
You can open a DESCRIPTION file with any text editor, such as Microsoft Notepad (Windows) or Apple TextEdit (Mac). The YouTube video description your DESCRIPTION file contains will then appear in the text editor.
