Managing encrypted cloud storage just got easier for Windows users. The new Optimize Storage feature gives you more control over how your synced folders behave and shows exactly what’s happening in File Explorer. It’s a simpler, smarter way to stay organized while keeping your files encrypted and easy to access on all your devices.
Let’s take a closer look at how it works and what other important updates have recently landed in Proton Drive for Windows.
What’s changing with the Optimize Storage feature?

The Optimize Storage setting gives you better visibility and control over your local folders synced to Proton Drive:
- When you enable it, File Explorer clearly labels the folders you’ve synced using the desktop app, making it easier to work in more folders scattered across your computer.

- You can decide whether folder contents are always available locally or offloaded automatically by Windows when storage is low — all while staying safely synced to Proton Drive.
- Just like before, if your synced folders contain large files (such as videos), you can right-click them in File Explorer to make them cloud-only and free up space.
What else is new in Proton Drive for Windows?
Here are a couple of recent updates you might have missed on the Windows app:
Available for Windows on ARM
If you’re using a Windows laptop or tablet with an ARM chip, you can enjoy the full Proton Drive experience optimized for your device:
- Securely access your files across all devices
- Keep your files safely stored in the cloud, protected by Proton Drive’s end-to-end encryption.
- Free up space on your device by making large, unused files cloud-only or by turning on Optimize Storage.
