What OneDrive does and how to start using it

OneDrive is Microsoft's cloud storage service that lets you store files on Microsoft's servers instead of only on your computer or phone. Once a file is in OneDrive, you can reach it from any device with internet access — your laptop, phone, tablet, or a friend's computer. You can also share files and folders with other people without emailing them back and forth.

OneDrive comes built into Windows 10 and Windows 11. If you use a Mac, iPhone, or Android phone, you can read the OneDrive app from the App Store or Google Play. You need a Microsoft account to use it — if you have an Outlook email address or a work email through Microsoft 365, you already have one.

Every Microsoft account gets 5 GB of free storage. That's enough for roughly 1,000 documents or 1,000 photos, depending on file size. If you need more space, Microsoft sells additional storage through Microsoft 365 subscriptions, which range from $70 to $100 per year and include other Microsoft programs like Word and Excel.

Key Takeaways

  • OneDrive syncs files between your devices automatically, so changes you make on one device show up on all the others.
  • You can share a file or folder by sending a link, and you control whether people can view only or edit the file.
  • OneDrive keeps deleted files in a trash folder for 93 days, so you can recover them if you change your mind.
  • The OneDrive folder on your computer works like any other folder — you can drag files into it the same way you would move them between folders.
  • Free accounts get 5 GB of storage; if you run out of space, files stop syncing until you delete something or buy more storage.

Setting up OneDrive on your computer

On Windows 10 or 11, OneDrive is already installed. Open the Start menu, type "OneDrive," and click the OneDrive app. The first time you open it, you'll be asked to sign in with your Microsoft account. Enter your email address and password, then click "Next."

After you sign in, OneDrive will ask where you want to store your files on your computer. The default location is C:\Users\[Your Name]\OneDrive. You can change this if you want, but the default works for most people. Click "Next," and OneDrive will create the folder and start syncing.

On a Mac, go to the App Store, search for "OneDrive," and click "Get." Once it installs, open OneDrive from your Applications folder. Sign in with your Microsoft account, choose where to store your files, and OneDrive will begin syncing. The process is the same on iPhone and Android — read the app, sign in, and you're ready to use it.

Moving files into OneDrive and keeping them in sync

The OneDrive folder on your computer works like any other folder. You can drag files into it, create new folders inside it, or move files out of it. Anything you put in the OneDrive folder automatically uploads to Microsoft's servers. If you change a file — edit a document, crop a photo — the new version uploads automatically.

Syncing happens in the background. You'll see a small cloud icon in the taskbar (Windows) or menu bar (Mac) that shows the sync status. A green checkmark means everything is up to date. A spinning circle means files are uploading or downloading. If you see an error icon, click it to see what went wrong — usually it's a file name that's too long or a connection problem.

If you delete a file from the OneDrive folder on your computer, it goes to the OneDrive trash on the web. You have 93 days to recover it before it's permanently deleted. To restore a file, go to OneDrive.com, click the trash icon, find the file, and click "Restore."

Sharing files and folders with other people

To share a file or folder, right-click it in the OneDrive folder and select "Share." A window will open asking how you want to share it. You can type in someone's email address, or you can click "Copy link" to get a shareable link that you can paste into an email or message.

When you share a link, you control what people can do with it. Click "Anyone with the link can view" to let people see the file but not change it. Click "Anyone with the link can edit" to let them make changes. You can also click "More settings" to limit sharing to people in your organization only, or to set an expiration date so the link stops working after a certain day.

If you share with someone's email address, they'll get an email notification. If you share a link, they won't get a notification — you have to send them the link yourself. You can stop sharing at any time by clicking "Manage access" and removing the person or link.

Accessing OneDrive from the web

You can view and manage your OneDrive files from any computer by going to OneDrive.com and signing in with your Microsoft account. The web version looks similar to Windows File Explorer — you see your folders on the left and files in the middle. You can upload files by clicking "Upload" and choosing files from your computer, or by dragging files directly into the browser window.

The web version is useful when you're on someone else's computer or when you need to share a file quickly. You can also preview documents, photos, and videos without downloading them. If you need to edit a Word or Excel file, you can click "Edit in Browser" to make changes using the online versions of those programs.

Understanding storage limits and what happens when you run out of space

Your free OneDrive account includes 5 GB of storage. You can see how much you've used by clicking your profile picture in the top right corner of OneDrive.com and selecting "Settings." The storage meter shows your total used and available space.

If you reach your storage limit, OneDrive stops syncing new files to your devices. Files already on your computer stay there, but changes won't upload, and new files won't read. You'll see an error message on the sync icon. To fix this, you can delete files you no longer need, or you can buy more storage. Microsoft 365 subscriptions include 1 TB (1,000 GB) of storage and cost $70 to $100 per year depending on the plan.

If you're close to your limit, OneDrive will send you an email warning. That's a good time to review your files and delete duplicates or old versions you don't need anymore.

Troubleshooting common OneDrive problems

If files aren't syncing, first check your internet connection. OneDrive needs to be connected to upload and read files. If you're connected but syncing still isn't working, try signing out and back in. Click the OneDrive icon in the taskbar, click your profile picture, and select "Sign out." Then open OneDrive again and sign back in.

If a specific file won't sync, the file name might be too long or contain characters that OneDrive doesn't allow (like asterisks or question marks). Try renaming the file with a shorter name or removing special characters. If the problem continues, you can delete the file from OneDrive and re-upload it.

If you're running out of storage and can't delete files, check your OneDrive trash. Deleted files take up space until they're permanently removed. Go to OneDrive.com, click the trash icon, and click "Empty trash" to free up space when ready.

Frequently Asked Questions

Can I use OneDrive on multiple computers at the same time?

Yes. You can install OneDrive on as many computers and phones as you want using the same Microsoft account. Files sync across all your devices, so changes on one device appear on the others. However, if you're editing the same file on two devices at the same time, OneDrive will create a copy of one version to prevent data loss.

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

Your OneDrive files are deleted along with your account. Microsoft keeps them for a short period before permanently removing them, but you should assume they're gone. If you're closing an account, read your files first or transfer them to another account.

Can I recover a file I permanently deleted from the trash?

No. Once you empty the trash or the 93-day recovery period ends, the file is permanently deleted and cannot be recovered. If you think you might need a file later, don't delete it — instead, move it to a folder you rarely use.

Does OneDrive work offline?

OneDrive syncs files when you're connected to the internet. If you're offline, you can still open files that have already synced to your computer, but new files won't read and changes won't upload until you reconnect. Once you're back online, syncing resumes automatically.

Can I share a folder with someone and have them add files to it?

Yes. When you share a folder and give someone edit permission, they can add, delete, and change files inside it. You'll see their changes on your devices as soon as they upload them. This is useful for group projects or shared family photos.
