A Microsoft file hosting and synchronization service.
Hi, I'm Diane and I'm happy to help you today.
- In my experience, freeing up space turned off the keep on my device setting and applied the change to all files and subfolders in that folder. The OneDrive app "frees up space" automatically after a period of time passes without using a file not marked 'keep on my device'.
- OneDrive should do that automatically. I tend to keep all the files I want to keep on the device in one folder path and if I need to free up space, I do it on other folders. Check your storage sense settings in Windows Settings. Start typing storage on the start menu and open storage settings to see if it is enabled.
Microsoft's article on storage sense: https://support.microsoft.com/office/use-onedrive-and-storage-sense-in-windows-10-to-manage-disk-space-de5faa9a-6108-4be1-87a6-d90688d08a48
The settings are grayed out because I'm running it now to verify it's not removing items marked to keep on my computer. you can control the settings for OneDrive and iCloud but not other cloud services (like dropbox).
Let me know how it goes, I'm here to help you further if needed.
