Microsoft has made it official that Windows Work Folders on-demand file access feature will be available in the Windows 10 Redstone 4 (Version 1803). By using this feature you can see and access all of your files on Windows 10 when using an enterprise managed file server with Work Folders.
You control which files are stored on your PC and available offline. The rest of your files are always visible and don’t take up any space on your PC, but you need connectivity to the Work Folders file server to access them.
For this feature you have to install Windows 10 build 17063 or later. To enable the on-demand file access feature, select the Enable on-demand file access setting in the Work Folders control panel applet or set the On-demand file access preference group policy setting.
How to enable the on-demand file access feature
There are three options to enable the on-demand file access feature:
Option #1: Work Folders setup wizard
When configuring Work Folders on a PC, verify the Enable on-demand file access on this PC setting is selected in the setup wizard.
Option #2: Work Folders control panel applet
If Work Folders is currently configured on a PC, open the Work Folders control panel applet and select the Enable on-demand file access setting.
Option #3: Work Folders group policy setting
Administrators can control the on-demand file access feature on PCs by setting the On-demand file access preference group policy setting.
These options can also be used to disable the on-demand file access feature if you want all files to be available offline on a PC.
File status in File Explorer
After enabling the on-demand file access feature, your files and folders stored in the Work Folders directory will have these statuses in File Explorer:
Available when online
Available when online files don’t take up space on your computer. You see a cloud icon for each Available when online file in File Explorer, but the file doesn’t download to your device until you open it. You can only open Available when online files when your device is connected to the internet. However, your Available when online files will always be visible in File Explorer even if you are offline.
Available on this device
When you open an Available when online file, it downloads to your device and becomes an Available on this device file. You can open an Available on this devicefile anytime, even without Internet access. If you need more space, you can change the file back to Available when online. Just right-click the file and select Free up space.
Always available on this device
Only files that you mark as Always keep on this device have the green circle with the white check mark. These files will always be available even when you’re offline. They are downloaded to your device and take up space.
