OneDrive is Microsoft's cloud storage service that stores your files on the internet instead of just on your computer

OneDrive is a cloud storage service made by Microsoft. Instead of keeping all your files on your computer's hard drive, you can store them on Microsoft's servers and access them from any device with an internet connection. You get a certain amount of free storage space — currently 5 GB for a free account — and can pay for more if you need it.

The basic idea is straightforward: upload a file to OneDrive, and you can open it on your phone, tablet, laptop, or any other device. You don't have to email files to yourself or carry a USB drive. If your computer crashes, your files are still safe on OneDrive's servers. If you're working on a document and someone else needs to see it, you can share a link instead of sending a copy.

OneDrive comes built into Windows 10 and Windows 11, so if you use a Windows computer, you already have it installed. You can also use OneDrive on Mac, iPhone, Android, and through a web browser at onedrive.live.com.

Key Takeaways

  • OneDrive stores your files on the internet so you can reach them from any device, not just the computer where you created them.
  • A free OneDrive account gives you 5 GB of storage; Microsoft 365 subscriptions include 1 TB (1,000 GB) per person.
  • Files you save to your OneDrive folder on your computer sync automatically to the cloud, so you don't have to upload manually.
  • You can share files and folders with other people by sending them a link, and you control whether they can view only or edit the file.
  • OneDrive is built into Windows and also works on Mac, iPhone, Android, and through any web browser.

How OneDrive syncing works on your computer

When you install OneDrive on your computer, it creates a folder called "OneDrive" (usually in your Documents or user folder). Any file you put in that folder automatically uploads to the cloud. This is called syncing. You don't have to think about it — it just happens in the background as long as your computer is connected to the internet.

The reverse also works: if you add a file to OneDrive from your phone or another computer, it downloads to your OneDrive folder on your main computer. This means the same files stay up to date across all your devices. If you edit a Word document on your laptop, save it, and then open OneDrive on your phone, you'll see the updated version.

You can choose which folders sync to your computer. If you have a lot of files on OneDrive but limited space on your laptop, you can tell OneDrive to keep only certain folders on your hard drive and store the rest only in the cloud. This is called Files On-Demand on Windows.

Storage space and what it costs

A free Microsoft account includes 5 GB of OneDrive storage. That's enough for documents, spreadsheets, and photos from a few trips, but fills up quickly if you store a lot of video or high-resolution photos.

If you need more space, Microsoft offers two main paths. A Microsoft 365 subscription (formerly called Office 365) costs money per month or year and includes 1 TB (1,000 GB) of OneDrive storage per person, plus access to Word, Excel, PowerPoint, and other Office apps. A standalone OneDrive storage plan gives you 100 GB or 200 GB for a smaller monthly fee, but does not include the Office apps.

Storage amounts and pricing vary by region and change over time, so check Microsoft's OneDrive pricing page for current options in your area. If you're a student or work for an organization with Microsoft accounts, you may have more storage included at no extra cost.

Sharing files and controlling who sees what

OneDrive makes it straightforward to share a file without emailing it. Right-click any file or folder in OneDrive, select "Share," and you can send a link to another person. You decide whether they can only view the file, or whether they can edit it too. You can also set an expiration date on the link so it stops working after a certain date.

The person you share with doesn't need a OneDrive account to open the file — they just click the link. If you want to stop sharing, you can delete the link or change the permissions anytime. OneDrive also shows you who has access to each file, so you know who can see what.

If multiple people need to work on the same document, OneDrive works with Microsoft 365 apps (Word, Excel, PowerPoint) to let everyone edit at the same time. You can see changes appear in real time as other people type, and there's no confusion about which version is the latest.

Security and what happens if you delete a file

OneDrive uses encryption to protect your files while they travel to Microsoft's servers and while they sit there. Your files are stored in Microsoft data centers with physical security and backup systems. If a hard drive fails, Microsoft has copies of your data in multiple locations.

If you accidentally delete a file from OneDrive, it goes to a Recycle Bin first. You have 93 days to restore it before it's permanently deleted. If you delete a file from your computer's OneDrive folder, it also goes to the Recycle Bin rather than being erased when ready, so you have time to recover it.

That said, OneDrive is not a backup service. If your account is hacked or compromised, the person with access could delete or change your files. It's a good idea to keep important files in more than one place — for example, an external hard drive or a second cloud service — especially for documents you can't afford to lose.

OneDrive on phones and tablets

The OneDrive app for iPhone and Android lets you view, upload, and share files from your phone. You can take a photo on your phone and have it automatically upload to OneDrive, so you don't lose it if your phone breaks. You can also open files stored on OneDrive without downloading them first, which saves space on your phone.

The mobile app works the same way as the desktop version: you can share files with a link, see who has access, and edit documents if you have Microsoft 365. The app also lets you scan paper documents with your phone's camera and save them as PDFs to OneDrive.

OneDrive versus other cloud storage services

OneDrive is one of several cloud storage options. Google Drive is free with a Google account and integrates with Google Docs, Sheets, and Slides. Dropbox is another popular choice. iCloud is built into Apple devices. Each service works similarly — store files in the cloud, sync to your devices, share with others — but they have different amounts of free storage, different pricing, and different apps they work best with.

If you use Windows and Microsoft 365, OneDrive is the most natural choice because it's already built in and works seamlessly with Word, Excel, and PowerPoint. If you use a Mac or iPhone, iCloud might be more convenient. If you use Google Workspace or prefer Google's apps, Google Drive makes more sense. There's no single "best" choice — it depends on what devices you use and what apps you work with most.

Frequently Asked Questions

Do I have to use OneDrive if I have Windows?

No. OneDrive comes with Windows, but you don't have to use it. You can turn off syncing, uninstall the app, or straightforward ignore it and use a different cloud service instead. Windows will work fine without OneDrive.

What happens to my OneDrive files if I stop paying for Microsoft 365?

Your files stay on OneDrive, but you lose access after a grace period (usually 60 days). If you downgrade to a free account, you keep your files as long as you stay under the 5 GB free limit. Files over that limit become inaccessible until you either delete some or pay for more storage again.

Can I use OneDrive on a work computer?

Yes, but check with your employer first. Many organizations set policies about cloud storage for security reasons. Your company may require you to use a different service, or may have OneDrive set up through a business account with different rules than a personal OneDrive.

Is OneDrive safe for passwords and sensitive documents?

OneDrive encrypts files in transit and at rest, but it's not designed as a password manager. For passwords, use a dedicated password manager like Bitwarden or 1Password. For very sensitive documents, consider whether cloud storage is the right choice at all, or use additional encryption on top of OneDrive.

How much internet speed do I need for OneDrive to work well?

OneDrive works on any internet connection, but syncing large files or many files at once is faster on a broadband connection. On a slow connection, syncing may take longer or pause. You can still access files on OneDrive through the web or app even on slow internet — they just won't read to your computer as quickly.
