The short answer
Yes. Rebuilt or re-downloaded automatically when needed.
What is it?
Discord’s web cache: images, avatars, emoji, GIFs and other content the app has loaded. It can reach several GB with active servers.
What happens if you delete it?
Rebuilt as you browse servers and chats; images load a little slower at first. Messages, settings and your login are not stored here.
How to remove it properly
Quit Discord completely (Discord › Quit Discord), then move ~/Library/Application Support/discord/Cache to the Trash.
Quit the app that uses it, then move it to the Trash. Empty the Trash when you’re sure.
How MoreRoom helps
MoreRoom recognises this item, shows its real size and when it was last used, and labels it “Safe to remove”. In the free version you can move it to the Trash in one click, with Undo; Pro collects every safe item at once.
