Sync your Files
First off, let’s see how we can sync our OneDrive and SharePoint files. When you sign into OneDrive, it usually syncs anyway. If you use SharePoint, just navigate to the page in your browser and hit the Sync button at the top of the page
Always Keep a Copy
If you right click on some files that you use a lot, or that you need to work on offline, rather than opening them all one-by-one, you can select multiple files or folders and choose ‘Always keep on this device’. This will download them and keep the local copy up to date if other people work on them.
Notice the Icon changes to a solid green circle.
Free Up Space
If you are running low on space (see also Free Up Space On You PC Using Storage Sense) you can right click any files or folders that have a green tick, which indicates that there is a copy on your hard disk as well as in the cloud and choose ‘Free up space’. This removes the local synced copy but doesn’t delete the file.
