OneDrive is cloud storage built into Windows 11 that syncs your files to Microsoft's servers

OneDrive is a cloud storage service that comes with Windows 11. It stores your files on Microsoft's servers instead of only on your computer's hard drive. When you save a file to OneDrive, it appears on any other device where you sign in with the same Microsoft account — your phone, tablet, or another computer.

The service runs in the background on Windows 11. You see it as a folder in File Explorer that looks and works like any other folder on your computer. When you add files to that folder, Windows automatically uploads them to the cloud. If you delete a file from OneDrive on one device, it disappears from all your devices.

OneDrive comes with 5 GB of free storage. If you need more space, you can buy additional storage through a Microsoft 365 subscription, which also includes Office apps like Word and Excel.

Key Takeaways

  • OneDrive syncs files between your Windows 11 computer and Microsoft's servers, so the same files appear on any device where you sign in.
  • You access OneDrive through a folder in File Explorer, and files sync automatically without you having to do anything after setup.
  • The free version includes 5 GB of storage; Microsoft 365 subscriptions add more space and include Office applications.
  • You can pause syncing temporarily, choose which folders to sync, or turn OneDrive off entirely if you do not want to use it.
  • Files deleted from OneDrive go to a recycle bin for 93 days before permanent deletion, giving you time to recover them.

How OneDrive syncing works on your computer

When you turn on OneDrive for the first time, you sign in with your Microsoft account. Windows then creates a OneDrive folder on your computer — usually at C:\Users\[Your Name]\OneDrive. Any file you put in this folder automatically uploads to Microsoft's servers.

The sync happens in the background. You do not have to click a button or wait for a dialog box. If you are connected to the internet, Windows watches the OneDrive folder and uploads changes within seconds or minutes, depending on file size and your connection speed. The same happens in reverse: if you add a file to OneDrive on your phone, it appears in the OneDrive folder on your computer.

A small icon next to each file shows its sync status. A blue circle with a checkmark means the file is fully synced. A circular arrow means it is still uploading. If you see a warning icon, there is a problem — usually that the file name is too long or contains characters Windows does not allow.

What files should and should not go in OneDrive

OneDrive works best for documents, photos, and other files you want to access from multiple devices. Word documents, spreadsheets, photos from your phone, and PDFs are all good candidates. If you store them in OneDrive, you can open them on your laptop, tablet, or phone without copying files around manually.

Do not put very large files or files that change constantly in OneDrive. Video files larger than a few gigabytes can take hours to upload and slow down your internet. process installation files and temporary files should stay on your computer's hard drive. If you use specialized software that creates many small temporary files, keeping those outside OneDrive prevents sync conflicts.

Avoid storing files in OneDrive if another person or program is also editing them at the same time on a different device. OneDrive can handle this in some cases — Microsoft Office files are designed for it — but other file types may become corrupted or create duplicate versions.

Controlling what syncs and when

You do not have to sync your entire computer to OneDrive. Right-click the OneDrive icon in the system tray (bottom right of your screen) and select Settings. Under the Account tab, click Choose folders. A window appears showing your OneDrive folders. Uncheck any folder you do not want to sync to this computer. This is useful if you have a laptop with limited storage and do not need every file on it.

To pause syncing temporarily — for example, if you are on a slow internet connection — right-click the OneDrive icon and select Pause syncing. You can pause for 2 hours, 8 hours, or until you restart your computer. When you resume, OneDrive catches up with any changes that happened while it was paused.

If you want to stop using OneDrive entirely, you can unlink your account. Right-click the OneDrive icon, select Settings, go to the Account tab, and click Unlink this PC. Your files stay on your computer, but they stop syncing to the cloud. Files already on Microsoft's servers remain there until you delete them through the OneDrive website.

Storage limits and what happens when you run out of space

The free OneDrive account includes 5 GB of storage. This covers a reasonable number of documents and photos, but fills up quickly if you store video or large design files. You can check how much space you have used by right-clicking the OneDrive icon and selecting Settings, then clicking the Storage tab.

When you reach your storage limit, OneDrive stops syncing new files. Files already synced remain on your computer and on the cloud, but you cannot add anything new until you delete files or buy more storage. A notification appears on your computer when you are close to the limit.

A Microsoft 365 subscription adds 1 TB (1,000 GB) of OneDrive storage and includes Office applications like Word, Excel, and Outlook. You can also buy OneDrive storage separately without a Microsoft 365 subscription, though this is less common.

Recovering deleted files from OneDrive

If you delete a file from the OneDrive folder on your computer, it goes to the OneDrive recycle bin, not your computer's recycle bin. Microsoft keeps deleted files for 93 days. To recover a file, right-click the OneDrive icon, select View online, and sign in to the OneDrive website. Click the recycle bin icon on the left side, find the file you want, and click Restore.

After 93 days, deleted files are permanently removed from OneDrive. There is no way to recover them after that point. If you delete a file by mistake, recover it as soon as you realize the error.

OneDrive and privacy

Your files on OneDrive are encrypted while they travel to Microsoft's servers and while they sit there. Microsoft can see the file names and folder structure, but the actual contents are protected. You can also encrypt individual files with a password before uploading them if you want an extra layer of security.

You control who can see your files. By default, only you can access your OneDrive. You can share individual files or folders with other people by right-clicking them in File Explorer, selecting Share, and entering their email address. You decide whether they can view only or edit the file.

Microsoft uses OneDrive data to improve its services and show you relevant ads, but it does not sell your files to third parties. If you have concerns about privacy, you can review Microsoft's privacy statement on their website, or you can choose not to use OneDrive and store files only on your computer's hard drive.

Frequently Asked Questions

Does OneDrive use my internet bandwidth to sync files?

Yes. OneDrive uploads and downloads files using your internet connection. Large files or many small files can slow your internet speed while syncing. If this is a problem, pause syncing during work hours and let it catch up at night, or uncheck folders you do not need on this particular computer.

Can I access OneDrive files if I am not connected to the internet?

Files in your OneDrive folder on your computer are always available offline. You can open and edit them without internet. When you reconnect, OneDrive uploads your changes. However, you cannot access files stored only in the cloud through the OneDrive website without an internet connection.

What happens to my OneDrive if I change my Microsoft password?

OneDrive continues to work. Your password change does not affect syncing. If you sign out of Windows, you will need to sign back in with your new password, but OneDrive itself does not require you to re-enter credentials.

Can I use OneDrive on a work computer?

Yes, but check with your employer first. Some companies restrict personal cloud storage on work devices for security reasons. If your company uses Microsoft 365 for business, they may have their own OneDrive setup with different rules and storage limits.

Does OneDrive work with external hard drives or USB drives?

No. OneDrive only syncs files stored in the OneDrive folder on your computer's main hard drive. Files on external drives or USB sticks do not sync automatically. You would have to copy them into the OneDrive folder to sync them to the cloud.
