Use OneDrive on Windows 10: Access Files Anywhere

Updated 7 November 2026 · Standard formula, shown below

Yes, you can use OneDrive on a Windows 10 PC to access your files from any device with an internet connection. OneDrive is built into Windows 10, and once you sign in with a Microsoft account, your files sync automatically to the cloud and to other devices where you use the same account.

What OneDrive Does on Windows 10

OneDrive is a cloud storage service that Microsoft includes with Windows 10. It works by creating a special folder on your PC (usually C:\Users\YourName\OneDrive) that mirrors the contents of your online OneDrive storage. When you put a file in that folder, it uploads to the cloud. When you change a file, the change syncs. When you delete a file, it moves to the OneDrive recycle bin in the cloud, not just your PC’s recycle bin.

You can access those same files from the OneDrive website (onedrive.com), from the OneDrive mobile app, or from another PC where you sign in with the same Microsoft account. This is useful if you work on a desktop at home and a laptop at work, or if you need to grab a document while you’re away from your desk.

How to Set Up OneDrive on Windows 10

OneDrive is already installed on most Windows 10 PCs. If you haven’t set it up yet, here’s what to do:

Click the OneDrive cloud icon in the notification area (bottom-right of the taskbar). If you don’t see it, click the up arrow to show hidden icons.
Sign in with your Microsoft account (the same account you use for Outlook, Xbox, or Windows). If you don’t have one, you can create a free account.
Choose where to put your OneDrive folder. The default location is fine for most people.
Select which folders to sync. You can sync everything or pick only the folders you need on this PC.
Click Next and then Open my OneDrive folder when the setup finishes.

If OneDrive isn’t installed, you can download it from the Microsoft website or from the Microsoft Store. It’s free for personal use with 5 GB of storage.

How to Access Files on Another Device

Once your files are synced, accessing them elsewhere is straightforward:

On the OneDrive website: Go to onedrive.com, sign in, and you’ll see all your files. You can view, download, upload, and even edit Office documents in the browser.
On another Windows PC: Sign in to OneDrive with the same Microsoft account, and your files will appear in the OneDrive folder. You can choose to sync only certain folders to save space.
On a Mac: Download the OneDrive app from the Mac App Store and sign in.
On a phone or tablet: Install the OneDrive app from the App Store (iOS) or Google Play (Android). You can view files and upload photos.

Files you edit on one device are updated on all devices, as long as you have an internet connection. If you’re offline, changes are saved locally and sync when you reconnect.

Files On-Demand: Save Space on Your PC

Windows 10 includes a feature called Files On-Demand that lets you see all your OneDrive files in File Explorer without downloading them to your PC. Each file shows a status icon:

Cloud icon (online-only): The file is only in the cloud. It takes up no space on your PC. You can open it if you have internet, and it will download on the spot.
White checkmark (locally available): The file is downloaded to your PC and takes up space. You can open it offline.
Green checkmark (always keep on this device): The file is always stored on your PC, even if you don’t use it for a while.

To turn on Files On-Demand, right-click the OneDrive icon in the notification area, go to Settings > Account tab, and check Save space and download files as you use them. This is especially useful if your PC has a small SSD.

Common Problems and How to Fix Them

OneDrive usually works quietly, but you might run into a few issues. Here are the most common ones and what to do:

OneDrive won’t start: Press Windows key + R, type onedrive, and press Enter. If that doesn’t work, search for OneDrive in the Start menu and open it. If it’s still not running, restart your PC.
Files not syncing: Right-click the OneDrive icon, choose Pause syncing and then Resume syncing. Check your internet connection and make sure you have enough free space on your PC and in your OneDrive account.
OneDrive is stuck on “Processing changes”: This can happen with many small files or a large number of changes. Give it time. If it lasts more than a few hours, restart OneDrive by right-clicking the icon and choosing Exit, then start it again.
“This file is too large” error: OneDrive has a 250 GB per-file limit for personal accounts. If you’re trying to sync a larger file, you’ll need to use a different method, like a USB drive.
OneDrive is using too much CPU: This usually happens during initial sync or after many changes. Let it finish. If it’s constant, check for a file that’s stuck and try renaming it or moving it out of the OneDrive folder.

OneDrive vs. Other Cloud Storage

OneDrive isn’t the only cloud storage option. Here’s how it compares to the main alternatives:

Google Drive: Gives you 15 GB free (shared across Gmail and Google Photos) versus OneDrive’s 5 GB. Google Drive integrates tightly with Google Docs. OneDrive integrates tightly with Microsoft Office and Windows.
Dropbox: Offers 2 GB free and is known for its simple, reliable sync. Dropbox has a more mature third-party app ecosystem, but OneDrive’s integration with Windows and Office is a strong advantage for many.
iCloud: Best for Apple users. It’s built into macOS and iOS, but the Windows app is less polished. OneDrive works well on both Windows and Mac.

If you use Microsoft Office (Word, Excel, PowerPoint), OneDrive is the most convenient because it lets you collaborate on documents in real time and automatically saves versions. You can also access your files from the Office apps on your phone.

Costs and Storage Plans

OneDrive is free with a Microsoft account, giving you 5 GB of storage. If you need more, Microsoft offers paid plans:

Microsoft 365 Personal: Includes 1 TB of OneDrive storage, plus the full Office apps (Word, Excel, PowerPoint, etc.) for one person. It costs about $70 per year.
Microsoft 365 Family: Includes 1 TB per person for up to 6 people, plus Office apps. It costs about $100 per year.
OneDrive Standalone: You can also buy 100 GB of OneDrive storage for about $2 per month, without Office.

These prices are typical and can change. If you already have a Microsoft 365 subscription, you already have 1 TB of OneDrive space.

Safety and Privacy

OneDrive files are encrypted in transit and at rest. Microsoft uses TLS (Transport Layer Security) to protect data as it travels between your PC and their servers, and the files are stored encrypted on their servers. You can also add two-step verification to your Microsoft account for extra security.

One important thing to know: if you share a file with someone, they can access it without needing your password. Always double-check the sharing settings before you send a link. Also, if you delete a file from OneDrive, it goes to the recycle bin and stays there for 30 days (for personal accounts), after which it’s permanently deleted.

A common misconception is that OneDrive is not secure because Microsoft can read your files. In fact, Microsoft’s privacy policy states that they do not use your OneDrive content for advertising and do not share it with third parties except to provide the service. However, if you have highly sensitive data, you might want to use a service with end-to-end encryption, like Tresorit or Sync.com.

Frequently Asked Questions

Can I use OneDrive without a Microsoft account?
No, you need a Microsoft account to use OneDrive. You can create one for free with any email address.

How do I know if a file is actually on my PC or only in the cloud?
Look at the status icons in File Explorer. A cloud icon means online-only, a white checkmark means downloaded, and a green checkmark means always kept on this device.

What happens if I run out of OneDrive storage?
Your files will stop syncing. You’ll see a warning in the OneDrive icon and on the website. You can either free up space by deleting files or upgrade your plan.

Can I access OneDrive files offline?
Yes, but only files that are marked as “locally available” or “always keep on this device.” Online-only files need an internet connection to open.

Is OneDrive the same as OneDrive for Business?
No. OneDrive (personal) is tied to your Microsoft account. OneDrive for Business is part of Microsoft 365 for organizations and is managed by your company’s IT department. The two are separate and don’t automatically sync with each other.

How do I stop OneDrive from syncing a folder?
Right-click the OneDrive icon, go to Settings > Account > Choose folders, and uncheck the folders you don’t want to sync. This removes them from your PC but keeps them in the cloud.
