Overview
You need to be running the Windows 10 Fall Creators update (v 1709) in order to have this feature.
OneDrive Files On-Demand helps you access all your files in OneDrive without having to download all of them and use storage space on your device.
When you turn on Files On-Demand, you’ll see all your files in File Explorer and get new information about each file. New files created online or on another device appear as online-only files, which don’t take up space on your device. When you’re connected to the Internet, you’ll be able to use the files like every other file on your device.

- How to change whether a file or folder is available offline

What's the difference between Locally Availbale Files and Always Available Files?
Microsoft explain about the different statuses fairly well in their Learn about OneDrive Files On-Demand article, but you might appreciate a little extra clarification of the difference between locally available files and always available files.
Your files will have these statuses in File Explorer:
Online-only files |
Online-only files don’t take up space on your computer. You see a cloud icon for each online-only file in File Explorer, but the file doesn’t download to your device until you open it. You can’t open online-only files when your device isn’t connected to the Internet. |
Locally available files |
When you open an online-only file, it downloads to your device and becomes a locally available file. You can open a locally available file anytime, even without Internet access. That means it is cached and available offline, but it might be removed if free disk space gets low. Unless you have a computer that is particularly short of disk space, or you intend to sync a huge amount of files in the future, it is likely these files will remain always available offline for you. However, if you want to be certain the file will always be available offline, you can right click on the file and choose Always keep on this device from the drop-down menu. If you need more space, you can change the file back to online only. Just right-click the file and select “Clear space.” |
Always available files |
Only files that you mark as "Always keep on this device" have the green circle with the white check mark. These files download to your device and take up space, but they’re always there for you even when you’re offline. This is similar to Locally Available Files, but you are guaranteed these files will always be available offline and won't be removed if disk space is low, or for any other reason. You should mark files that you know you definitely want to be available always, online or offline, as Always keep on this device. If you need more space, you can change the file back to online only. Just right-click the file and select “Clear space.” |

How to Change Whether a File or Folder is Available Offline
|
Right-click a file or folder in your OneDrive To mark a file as Online-only (Blue cloud icon) click on Clear Space To mark a file as Always Available (solid green circle) click on Always keep on this device
|
|
| If you mark a file as Always Available (solid green circle), you will also see that there is a tick beside 'Always keep on this device' on the context menu. If you click Always keep on this device again it will clear that tick and the status will change to a clear green circle containing a green tick, meaning the file is 'locally available'. That means it is cached and available offline, but it might be removed if free disk space gets low. |  |
