OneDrive is cloud storage built into Windows that syncs your files to Microsoft's servers

OneDrive is a folder on your computer that automatically copies everything in it to the internet. When you save a file to OneDrive, Windows uploads it to Microsoft's servers in the background. If you sign in to OneDrive on another device—a laptop, tablet, or phone—you see the same files there. It is included free with Windows 10 and Windows 11, and it comes with 5 gigabytes of storage at no cost.

You do not have to use it. OneDrive runs quietly in the background, but you can turn it off, pause it, or ignore it entirely. Many people never touch it and have no problems. Others use it as their main way to back up important documents, photos, and work files.

Key Takeaways

  • OneDrive is a cloud storage service that syncs files from your computer to Microsoft's servers, so you can reach them from other devices.
  • You get 5 gigabytes free with Windows; Microsoft offers paid plans with more storage if you need it.
  • Files in your OneDrive folder upload automatically when your computer is connected to the internet, but you can pause or stop syncing at any time.
  • OneDrive is optional—you can disable it completely if you prefer not to use cloud storage.
  • Deleted files stay in OneDrive's recycle bin for 93 days before they are permanently removed.

Where OneDrive lives on your computer

OneDrive creates a folder in your user directory, usually at C:\Users\[Your Name]\OneDrive on Windows. You can see it in File Explorer on the left sidebar—it looks like a cloud icon. Any file you put in that folder is automatically uploaded to Microsoft's servers.

You can also save files directly to OneDrive from inside other programs. Microsoft Office (Word, Excel, PowerPoint) has a "Save to OneDrive" option. Some other programs let you choose OneDrive as a save location too. The folder itself works like any other folder on your computer—you can create subfolders, move files in and out, and delete things.

How syncing works and what it means for your files

Syncing means OneDrive keeps copies of your files in two places at once: on your computer and on Microsoft's servers. When you save a file to the OneDrive folder, Windows uploads it automatically. When you change a file, the new version uploads too. If you delete a file from OneDrive on your computer, it moves to the OneDrive recycle bin online—it does not disappear when ready.

Syncing only happens when your computer is connected to the internet. If you are offline, you can still open and edit files in your OneDrive folder (they are stored locally on your computer), but the changes will not upload until you reconnect. Once you go back online, Windows syncs automatically without asking you.

You can see the sync status of any file by looking at the icon next to its name in File Explorer. A checkmark means the file is fully synced. A circular arrow means it is uploading or downloading right now. A warning symbol means something went wrong—usually because the file name is too long or contains characters OneDrive does not allow.

Storage limits and what happens when you run out of space

The free OneDrive account gives you 5 gigabytes of storage. That is enough for thousands of documents and spreadsheets, but not for a large photo library or video collection. If you reach your limit, OneDrive stops syncing new files until you delete something or buy more storage.

Microsoft offers paid plans through Microsoft 365 (formerly Office 365). A Microsoft 365 Personal subscription includes 1 terabyte of OneDrive storage and costs money per month or per year—the price varies by region and changes over time. You can also buy OneDrive storage separately without buying the full Microsoft 365 suite, though that option is less common.

You can check how much storage you are using by clicking the OneDrive icon in the system tray (bottom right of your screen) and selecting "Help & Settings" > "Settings" > "Storage".

Turning OneDrive off or pausing it

If you do not want to use OneDrive, you can pause syncing temporarily or turn it off completely. To pause, right-click the OneDrive icon in the system tray and select "Pause syncing". Choose how long you want to pause—1 hour, 8 hours, or until you restart your computer. Syncing resumes automatically after that time.

To turn OneDrive off entirely, go to Settings > Accounts > Sync your settings and toggle off "OneDrive". You can also unlink your Microsoft account from OneDrive, which stops syncing but leaves your files on your computer. The OneDrive folder itself stays there—it just stops uploading to the cloud.

Uninstalling OneDrive completely is harder on Windows 10 and 11 because it is built into the system, but it is possible through the Settings app or by using the command line. Most people find it easier to just leave it installed and paused if they do not want to use it.

OneDrive and your privacy

When you use OneDrive, your files are stored on Microsoft's servers. Microsoft says it does not read your files or use them for advertising, but your data is subject to Microsoft's privacy policy and any laws that explore in your country. If you are uncomfortable storing files on the internet, you can keep OneDrive turned off and store everything locally on your computer instead.

Files in your OneDrive are private by default—only you can see them. You can share a file or folder with other people by right-clicking it and selecting "Share", which generates a link. You control whether people can view only or edit the file, and you can turn off the link at any time.

What to do if OneDrive is using too much of your internet or computer resources

OneDrive syncing can slow down your computer or use a lot of bandwidth, especially if you have a large number of files or a slow internet connection. If that is happening, you can limit how much bandwidth OneDrive uses. Right-click the OneDrive icon in the system tray, select "Help & Settings" > "Settings" > "Network", and choose a bandwidth limit.

You can also choose which folders to sync. If you have a OneDrive folder with thousands of files but only need a few of them on this computer, you can tell OneDrive to sync only those folders. Go to Settings > Accounts > Sync your settings, find OneDrive, and select "Manage sync settings". Uncheck the folders you do not need on this device.

Frequently Asked Questions

Is OneDrive the same as OneDrive for Business?

No. OneDrive (the free version) is for personal use. OneDrive for Business is a separate service for work, usually provided by your employer through a Microsoft 365 subscription. They work similarly but are separate accounts and storage spaces.

What happens to my OneDrive files if I delete my Microsoft account?

Your files stay on Microsoft's servers for a limited time (usually 90 days), but you lose access to them. After that period, Microsoft deletes them. If you want to keep your files, read them to your computer before you delete your account.

Can I use OneDrive on a Mac or phone?

Yes. Microsoft offers OneDrive apps for Mac, iPhone, and Android. You sign in with the same Microsoft account, and you see the same files across all your devices. The Mac version works similarly to the Windows version.

Does OneDrive back up my entire computer?

No. OneDrive only syncs files you put in the OneDrive folder. If you want to back up your entire computer, you need a separate backup tool. Windows includes a built-in backup feature called File History that can help with this.

Why is OneDrive showing a warning icon on some of my files?

Usually because the file name is too long, contains special characters that OneDrive does not allow, or the file is locked by another program. Rename the file to something shorter and simpler, or close the program using it, and syncing should resume.
