When you use OneDrive for Business on Windows, files can exist in three distinct states: local, online-only, or always available. Knowing which state a file is in helps you manage disk space and offline access. This article explains what each status means and how to check a file’s availability at a glance. You will learn to read the sync status icons and adjust file availability settings directly from File Explorer.
Key Takeaways: How to Identify OneDrive File States in File Explorer
- File Explorer column headers > Status: Right-click column headers and add the Status column to see “Local”, “Online-only”, or “Always available” text for every file.
- OneDrive tray icon > Sync activity: Opens the activity center that lists recent sync changes and file status transitions.
- Right-click file > Free up space or Always keep on this device: Changes a file from local to online-only or from online-only to always available without affecting other files.
OneDrive File States: Local, Online-Only, and Always Available
OneDrive for Business uses Files On-Demand to let you access all your cloud files without downloading them all to your hard drive. This feature saves local storage while keeping every file visible in File Explorer. Each file displays a status icon in the Overlay column that tells you whether the file is physically stored on your device or only in the cloud.
The three states work as follows:
Online-only files show a cloud icon. The file exists only in the OneDrive cloud. It takes almost no space on your local drive. You can open it only when you have an internet connection. When you open an online-only file, OneDrive downloads it on demand and then marks it as locally available.
Locally available files show a solid green checkmark. The file is fully downloaded to your device and takes up disk space. You can open it offline without any delay. OneDrive keeps the local copy in sync with the cloud version.
Always available files show a green circle with a white checkmark. This is a special local state that you set manually. The file stays on your hard drive even if you haven’t opened it recently. OneDrive never frees up space from an “always available” file unless you change its status back.
How to Check a File’s Status in File Explorer
The quickest way to see a file’s state is by looking at the overlay icon next to the file name. If the icons are missing or unclear, you can add the Status column to your File Explorer view.
- Open File Explorer and navigate to your OneDrive folder
Press Win + E on your keyboard, then click OneDrive in the left navigation pane. Your OneDrive folder opens. - Add the Status column
Right-click any column header such as Name or Date modified. In the menu that appears, click Status. A new column labeled Status appears on the right. - Read the file status
Each file now displays one of these values in the Status column: Online-only, Locally available, or Always available. The text matches the overlay icon shown to the left of the file name. - Sort or group by status
Click the Status column header to sort files by their availability state. This helps you quickly find all online-only files that you might want to make always available.
If the Status column does not appear, ensure Files On-Demand is enabled. Go to OneDrive settings by right-clicking the OneDrive cloud icon in the system tray, selecting Settings, then clicking the Sync and backup tab. Under Files On-Demand, make sure the toggle is set to On.
How to Change a File’s Availability State
You can change a file’s state manually without affecting other files in the same folder. Two options are available directly from the right-click context menu.
Make an Online-Only File Always Available
- Right-click the file or folder in File Explorer
Navigate to the file that shows a cloud icon or reads Online-only in the Status column. - Select Always keep on this device
From the context menu, click Always keep on this device. OneDrive immediately downloads the file to your local drive. The icon changes to a green circle with a white checkmark, and the Status column updates to Always available.
Free Up Space from a Locally Available File
- Right-click a file that shows a solid green checkmark
This file is currently stored locally and consumes disk space. - Select Free up space
From the context menu, click Free up space. OneDrive removes the local copy but keeps the file visible in File Explorer. The icon changes to a cloud, and the Status column changes to Online-only.
You can apply these same actions to entire folders. Right-click a folder and choose Always keep on this device to make every file inside it always available. Choose Free up space to revert all files in the folder to online-only.
Common Mistakes When Checking File Status
Overlay icons are missing or showing wrong symbols
If you see no overlay icons or the icons appear incorrect, OneDrive might be paused or Files On-Demand may be disabled. Check the OneDrive sync status in the system tray. If the cloud icon shows a pause symbol, click it and select Resume syncing. If Files On-Demand is turned off, all files will show a solid green checkmark even if they are not fully downloaded. Re-enable Files On-Demand in OneDrive settings to restore accurate status icons.
The Status column shows blank values for some files
This happens when File Explorer is still indexing the folder or when the OneDrive sync engine is processing changes. Wait a few seconds and refresh the view by pressing F5. If blank values persist, restart File Explorer by right-clicking the Start button, selecting Task Manager, finding Windows Explorer in the list, clicking Restart, and then navigating back to your OneDrive folder.
Always keep on this device option is grayed out
This occurs when the file is already set to Always available. It can also happen if the file is currently syncing. Wait for the sync to finish. If the option remains grayed out, check that you have sufficient free disk space and that the file is not open in another program.
Online-Only vs Always Available: Key Differences
| Item | Online-only | Always available |
|---|---|---|
| Overlay icon | Cloud | Green circle with white checkmark |
| Local disk usage | Zero bytes | Full file size |
| Offline access | Requires internet to open | Available without internet |
| How to set | Right-click > Free up space | Right-click > Always keep on this device |
| OneDrive auto-management | Can be freed automatically if storage is low | Never freed automatically |
Use online-only for files you rarely need offline. Use always available for critical files you access daily or when traveling without reliable internet.
You can now identify whether any file in OneDrive for Business is stored locally, online-only, or set to always available by reading the overlay icons or the Status column in File Explorer. To manage disk space efficiently, use the Free up space command on files you no longer need offline and the Always keep on this device command on essential files. For a quick overview of all files, sort the Status column to group files by availability state. If you frequently work offline, consider setting your entire project folder to Always keep on this device before disconnecting from the internet.
