Getting Started with Cowork
Claude Cowork transforms how you work with documents and files. But before you can organize folders, analyze spreadsheets, or generate reports, you need to set up the environment. Let's get started.
Requirements
Before you begin, ensure you have:
| Requirement | Details |
|---|---|
| Subscription | Claude Pro, Max, Team Premium, or Enterprise (free tier and Team Standard don't include Cowork) |
| Platform | macOS or Windows (x64) |
| Claude Desktop | Latest version from claude.ai/download |
| Work to do | Documents, files, or data you want to work with |
Why the subscription requirement? Cowork's agentic capabilities—filesystem access, document processing, persistent context—require significant infrastructure. The Pro and Max tiers support this enhanced functionality.
Installation Steps
Step 1: Install Claude Desktop
- Visit claude.ai/download
- Download the Claude Desktop app for your platform (macOS or Windows)
- Install and launch the application
- Sign in with your Anthropic account (Pro, Max, Team Premium, or Enterprise)
The Desktop app is your gateway to Cowork. Unlike the web interface, it has direct access to your filesystem with your permission.
Step 2: Enable Cowork Mode
Claude Desktop has three tabs across the top of the window:
- Chat: Standard conversation (web-like behavior)
- Cowork: Agentic mode with filesystem access
- Code: Developer-focused terminal interface
Select the Cowork tab when you want Claude to work with files on your computer. You'll know you're in Cowork mode when you see the folder access panel.
Step 3: Grant Folder Access
The first time you use Cowork, Claude will ask for folder access. This is a critical security boundary—Claude can only access folders you explicitly approve.
To grant access:
- Click the "Grant Access" or "Choose Folder" button
- Navigate to the folder you want to work with
- Confirm the access request
Best practices for folder access:
- Create a dedicated workspace folder for Cowork projects
- Don't grant access to sensitive system directories
- Start with a specific project folder, not your entire home directory
- Revoke access when you're done with sensitive work
The Cowork Interface
When you're in Cowork mode, the interface has three main sections:
Conversation Panel
Where you communicate with Claude. This works like standard chat, but with enhanced context awareness:
- Claude knows about files in your approved folders
- Previous conversations in the session inform context
- You can reference files by name without uploading
Execution Panel
Shows what Claude is actually doing:
- Files being read or written
- Operations in progress
- Warnings or errors
This is your visibility into Claude's actions. You see exactly what will change before it happens.
Artifacts Panel
Where Claude presents results:
- Generated documents
- Analysis results
- Created files
You can preview, download, or open artifacts directly from this panel.
Your First Cowork Task
Let's put Cowork to work with a practical first task: organizing a messy folder.
Setup: Pick a real folder you already have — your Downloads folder, a project folder with mixed files, or any workspace that could use organization. Grant Claude Cowork access to that folder.
Task: In Claude Cowork, ask:
"Organize these files by type: put all text files in a 'docs' folder, all Word documents in an 'office' folder, and all images in an 'images' folder. Use consistent naming."
What happens:
- Claude reads the directory to see what files exist
- Claude proposes an organization plan in the Execution Panel
- You review and approve the plan
- Claude creates folders and moves files
- Claude confirms completion
Why this matters: You didn't write any code. You described what you wanted, and Claude executed it safely with your approval.
Understanding the Approval Workflow
Cowork doesn't execute blindly. Every significant operation requires your approval:
| Operation Type | Requires Approval | Example |
|---|---|---|
| Read files | No | Claude reads to understand context |
| Create new files | Yes | Claude shows what will be created |
| Modify existing files | Yes | Claude shows diff or summary |
| Delete files | Yes | Claude asks for explicit confirmation |
| Move/rename files | Yes | Claude shows before/after paths |
This approval workflow is your safety net. Claude proposes, you approve, then Claude acts.
Working with Documents
Cowork shines when working with document formats. Try this:
Task: Create a simple Word document with structured content.
"Create a Word document called 'project-plan.docx' with these sections: Overview, Timeline, Budget, and Team. Add placeholder content for each section."
Claude will:
- Create the .docx file
- Add the section headers
- Generate relevant placeholder content
- Show you the result in the Artifacts panel
You can then open the document in Word to see a properly formatted file—not just text, but actual document structure.
Common First Tasks
After completing the initial setup, try these tasks to explore Cowork's capabilities:
| Task | Prompt | What You'll Learn |
|---|---|---|
| Batch rename | "Rename all files in this folder to use YYYY-MM-DD format based on their creation date" | Pattern-based file operations |
| Document summary | "Read all the .txt files in this folder and summarize the key points from each" | Multi-document analysis |
| Format conversion | "Convert this Word document to a plain text file while preserving the structure" | Document format handling |
| File cleanup | "Find all duplicate files in this folder (by content) and move them to a 'duplicates' folder" | Advanced file operations |
Safety Tips
As you start using Cowork, keep these safety principles in mind:
- Start Small: Begin with a test folder, not your important documents
- Review Carefully: Always read the execution plan before approving
- Backup First: Cowork is powerful—back up important data before major operations
- Revoke Access: Remove folder permissions when you're done with a project
- Watch the Panel: Keep an eye on the Execution Panel to understand what Claude is doing
Troubleshooting
Issue: Cowork mode doesn't appear
- Ensure you're on Pro, Max, Team Premium, or Enterprise subscription
- Update Claude Desktop to the latest version
- Sign out and sign back in
Issue: Folder access denied
- macOS: Check Privacy Settings (System Settings > Privacy & Security > Files and Folders) and grant Claude Desktop permission
- Windows: Ensure you have admin privileges for the initial setup
- Try granting access to a more specific folder
Issue: Claude Desktop won't launch on Windows
- Verify you are running Windows x64 (ARM is not supported)
- Windows S Mode is not supported—switch to standard Windows first
- Run the installer as Administrator if the initial install fails
Issue: Operations are slow
- Large folders take time to scan—be patient with the initial read
- Complex operations (like analyzing hundreds of files) may take time
- Check the Execution Panel for progress information
Try With AI
Plan Your First Real Cowork Task:
"I work with [describe your actual documents and files]. What is one task I do weekly that involves organizing, processing, or creating files? Design the Cowork prompt I would use — include what folder to grant access to, what outcome I want, and what constraints matter (e.g., don't delete anything, preserve folder structure)."
What you're learning: Task design for agentic AI — translating a real work need into a specific, safe Cowork prompt. The folder access decision and constraint specification are the skills that make Cowork effective from day one.
Test the Approval Workflow:
"In your granted folder, ask Claude to rename 3 files using a consistent naming pattern. Before approving, read the Execution Panel carefully: What files will change? What will the new names be? Approve only if every change looks correct. Then describe what you observed in the propose-approve-execute cycle."
What you're learning: Approval workflow fluency — the habit of reading the execution plan before clicking approve. This is the single most important safety skill for Cowork, and practicing it on a small operation builds the reflex before you attempt bulk operations.
What's Next
Now that you're set up, the next lessons explore practical workflows: organizing files, processing documents, integrating with browsers, and using connectors. You'll see Cowork handle real-world tasks that save hours of manual work.
