Claude Cowork: How AI Freed 60GB of Storage on My Mac

No matter how much storage space I get on a device, I always seem to fill it up. Beyond my habit of hoarding screenshots I’ll likely never look at again, the biggest problem is that cleaning up digital clutter feels so tedious that I’d rather just ignore the “disk is almost full” warnings. And frankly, I don’t even understand where to start! Since getting my M2 MacBook Air, I hadn’t bothered with a proper cleanup.

A few weeks ago, I used Claude Cowork to organize my extremely messy Mac, and it occurred to me: if it can sort through all that chaos and make it easier to navigate, it could probably assist me actually clear things out. That’s exactly what I decided to do, and I ended up freeing nearly 60GB of space from files I didn’t even remember existed.

What is Claude Cowork?

It’s Claude, but it can actually touch your files

Claude Cowork is a relatively new feature from Anthropic, the company behind the Claude chatbot. It bridges the gap between Claude Code – Anthropic’s developer tool – and users who aren’t comfortable with coding. Claude Code is an “agentic AI” that can read, write, and execute code directly in a terminal. Because it has access to the file system, developers have been using it for tasks beyond coding, like organizing folders, renaming files, and compiling research.

While powerful, Claude Code is geared towards those comfortable with a command-line interface. Anthropic recognized this limitation and created Cowork to bring the same capabilities to a more user-friendly environment. Cowork, integrated into the Claude Desktop app, allows you to grant Claude access to folders on your computer and then describe what you want it to do. It then reads, edits, creates, and organizes files automatically, breaking down each task into steps and displaying its progress.

As of March 2026, Cowork is available for both macOS and Windows, but it’s currently in research preview. In other words Anthropic is still working on ensuring agent safety. The feature is also exclusive to Claude’s paid subscription plans.

Reclaiming 60GB: A Step-by-Step Process

Three years of “I’ll organize this later” finally caught up with me

Given that Cowork can access folders and files on my local machine, I started with a simple prompt detailing my goal – clearing up storage – to see what it would suggest. I asked it to find duplicate files, old installers, large files I didn’t need, and anything that looked like clutter. Here’s the exact prompt I used:

Hey! Go through my MacBook. Find duplicate files, old installers, large files I probably don’t need, and anything that looks like clutter. List everything you’d recommend deleting with file sizes, but DO NOT delete anything. Just give me the report.

The instruction to not delete anything was crucial. Because Cowork is still in research preview, and because it’s an AI, there’s a risk of it deleting something important. Throughout the process, I consistently instructed Claude to only provide reports, not seize action.

After sending the prompt, it asked for access to my home folder, which includes common clutter spots like Downloads, Desktop, and Caches. It then ran scans and identified 17 GB of reclaimable space across those locations. This included Disk Image (.dmg) and Package (.pkg) files, duplicate downloads (apparently, I’d installed Zoom and Logi Options seven times!), app caches, and large media files. The findings were presented in an HTML file, which I found to be a convenient way to review everything before deciding what to delete.

I then sent the following prompt:

Look through my Documents, Desktop, and Downloads folders. Find any files or folders I haven’t opened or modified in over 2 months. Group them by size and tell me what they are, but don’t delete anything.

This yielded another report, and then I asked Cowork to provide a breakdown of my Downloads and Documents folders by file type, to pinpoint where the bulk of the storage was going. I also asked it to scan my Applications folder.

The results were revealing. I found a 6.1 GB WhatsApp desktop app (which I rarely use), 2.9 GB of Xcode Simulators (also unused), 1.1 GB of CapCut cached data, and more. I even asked it to look for unboxing videos, and it found a 5.5 GB folder of months-old footage, a 2.4 GB folder of iPhone transfers, and 1.5 GB of random press kits.

Finally, I asked Cowork to scan several system directories – ~/Library/Logs, ~/Library/Mail, ~/Library/Messages, ~/Library/Group Containers, ~/Library/Containers, ~/Library/Developer, ~/.Trash, ~/Movies, ~/Music, and ~/Pictures – uncovering even more unused applications and folders.

In total, Cowork identified roughly 60 GB of reclaimable space. Given that my MacBook Air has only 256 GB of storage, this represented nearly a quarter of my entire drive.

This would have taken me forever

Could I have done this manually? Yes. Would I have? Probably not. Knowing my habits, I would have continued to postpone the task, letting files accumulate and ignoring the “disk is almost full” warnings while only deleting the most obvious offenders.

The Implications of Agentic File Management

Claude Cowork represents a significant step forward in making the power of “agentic AI” accessible to a wider audience. Agentic AI refers to systems that can autonomously perform tasks on behalf of a user, rather than simply responding to specific commands. The ability to grant an AI access to your file system and instruct it to perform complex organizational tasks has the potential to dramatically improve productivity and free up valuable storage space. However, it also raises important questions about security and trust.

The current research preview status is a prudent approach. Anthropic is actively working on improving the safety of these agents, ensuring they don’t inadvertently delete or modify important files. The limitation to paid subscribers also allows Anthropic to carefully control access and gather feedback from a smaller, more engaged user base.

The success of Cowork could pave the way for similar features in other AI assistants, potentially transforming how we manage our digital lives. However, it’s crucial to remember that these tools are not foolproof. Users should always carefully review any proposed changes before allowing an AI to take action, and maintain regular backups of their important data. The MacBook Air M2, for example, comes with options for external backups, and Time Machine is a robust built-in solution.

What Comes Next

Anthropic is continuing to refine Cowork based on user feedback. Expect to see improvements in its accuracy, safety, and user interface. The company is also likely to explore ways to expand its capabilities, such as adding support for more file types and automating more complex tasks. The long-term goal is to create an AI assistant that can seamlessly manage your digital life, freeing you up to focus on more important things. The current research preview phase will be critical in identifying and addressing potential risks before a wider rollout.
