We do this so that we can keep your files available locally as much as possible. Storage Sense will only dehydrate files until there’s enough space freed for Windows to run smoothly. Any files that you have not used, in the last 30 days, will be eligible for dehydration when your device runs low on free space. Here, you can turn Storage Sense on by clicking the toggle button. Turn on Storage Sense in Storage Settings To enable dehydration, navigate to the Settings app from the start menu.

When connected to the internet, you’ll be able to use online-only files just like any other file. Your online-only files will still be visible on your device. Your files will still be safe in OneDrive and represented as placeholders on your device. Storage Sense now has the capability to automatically free up disk space by making older, unused, locally available OneDrive files be available online-only. You may no longer need those files to be locally available. If you have a large amount of OneDrive content that you’ve viewed and edited, you may find yourself in a situation where those files are available locally and the cached content takes up disk space. OneDrive Files On-demand gives you easy access to your OneDrive files without taking up storage space.
