2.2 · Working With Files
You gave Cowork a file. It did something with it. But where did the result actually go?
This is one of the most important things to understand about Cowork, and it's different from every browser-based AI you've used.
When Cowork creates something, it creates an actual file on your computer. Not a chat response you need to copy. Not a temporary preview. A real file, in a real folder, that you can open with any app.
Ask Cowork to "create a summary document from these notes" and you'll find a new file in your project folder. Something like meeting-summary.md or summary.txt. You can open it in Word, Notion, Google Docs, whatever you normally use.
New files appear in your project folder. That's the folder Cowork is currently pointed at. If you're not sure which folder that is, ask: "What folder are we working in?"
You can track what Cowork is working with in the Context panel on the right side of the interface.
Not everything creates a file. There's a simple pattern:
If you want a file when Cowork gives you a chat response, just say: "Save that as a file called summary.md." It will.
Cowork doesn't just create new files. It can also edit existing ones. Say "Fix the typos in meeting-notes.txt" and it'll update the file directly.
The first time Cowork wants to make changes to files in your folder, it'll ask for permission. Once you allow it, that applies to all files in the folder for that session. Destructive actions like deleting files always get a separate permission check, no matter what.
Head to the game and play through the Level 1 demos. You'll see Cowork read files, create new ones, and produce results that land right in your project folder.
