Access OneDrive files without consuming local storage
Offline access and On-Demand files are extremely useful OneDrive features. However, it’s important to understand the difference between the two before you decide which one to use.
Offline Access files are downloaded and synced to your personal computer. This way you can access them even when you’re not connected to the internet.
On-Demand files are available only in the cloud and they are not downloaded to your personal computer. However, you can easily access them through File Explorer on your personal computer if you’re online. This saves you the time to navigate between apps.
You can learn more about these features and how to configure them using the Offline Access and On-Demand guides from Microsoft.
