How to Manage OneDrive Storage: Free Up Space in Minutes

Quick Answer: To manage your OneDrive storage, check what is using the most space at onedrive.live.com/options/OneDrive → Manage Storage. Delete large files you no longer need, empty the Recycle Bin (it still counts against your storage), turn on Files On-Demand to store files in the cloud without using local disk space, and remove old version history for large files. Most people can free up 20–40% of their storage in under 10 minutes.

Key Takeaways

• The Recycle Bin is the most overlooked storage issue – deleted files still count against your quota until the bin is emptied. Check it first.
• Files On-Demand is the biggest storage trick most people never use – it lets you access all your OneDrive files on your PC without them taking up local disk space.
• Microsoft 365 Business subscribers get 1TB per user – personal free accounts get 5GB.
• Version history for large files can quietly eat huge amounts of storage – each version of a 500MB file takes up 500MB of your quota.
• If you are an IT admin managing storage for a team, the Microsoft 365 Admin Centre gives you a usage report for every user in seconds.
• Upgrading storage is available but unnecessary for most users – clearing the Recycle Bin and removing duplicate files alone typically frees up enough space.

Step 1: Check How Much OneDrive Storage You Have and What Is Using It

Before you delete anything, find out exactly where your storage stands.

For personal OneDrive accounts (OneDrive.com):

1. Go to onedrive.live.com
2. Click the gear icon (Settings) in the top right
3. Click OneDrive settings → More OneDrive settings
4. Select Storage – you will see a bar showing how much is used and how much remains

For Microsoft 365 Business accounts (OneDrive for Work):

1. Open OneDrive in your browser via office.com
2. Click the gear icon → OneDrive settings
3. Scroll to Storage to see your current usage

Or simply visit onedrive.live.com/options/OneDrive – this works for both account types.

Step 2: Empty Your Recycle Bin (Do This First)

This is the fastest way to recover storage – and the step most people skip.

When you delete a file in OneDrive, it goes to the Recycle Bin. The file is deleted from your view – but it still counts against your storage quota. It stays there for 93 days before it is automatically permanently deleted.

If you deleted a 2GB folder of old project files last month, that 2GB is still eating your storage right now.

How to empty the OneDrive Recycle Bin:

1. Open OneDrive in your browser
2. Click Recycle Bin in the left sidebar
3. If you are sure you do not need anything in there, click Empty Recycle Bin at the top
4. Confirm the deletion

Or selectively delete large items: sort the Recycle Bin by Size (click the column header) and permanently delete the largest files first.

Step 3: Find and Delete the Largest Files

You do not need to review thousands of files to make a meaningful dent in your storage. The largest 10–20 files usually account for the majority of space used.

How to find your biggest files:

On web (OneDrive.com):

1. Open OneDrive in your browser
2. In the search bar, search for * (asterisk – this shows all files)
3. Click Sort by → File size (largest first)
4. Review and delete files you no longer need

On Windows (File Explorer):

1. Open File Explorer → OneDrive folder
2. In the search box, type: size:>100MB
3. This shows every file over 100MB – the quick wins for storage recovery

Common large files people forget about:

• Old video recordings from Teams meetings (saved to OneDrive)
• ISO files or software installers downloaded months ago
• Duplicate copies of large presentations or spreadsheets
• Old project folders that have been completed and archived

Step 4: Turn On Files On-Demand (Your Biggest Space Saver)

This is the most powerful OneDrive storage feature most users have never heard of.

What is Files On-Demand?

Without Files On-Demand, every OneDrive file you have synced to your PC exists as a full copy on your hard drive. If your OneDrive contains 50GB of files, your PC hard drive uses 50GB for those files.

With Files On-Demand enabled, the files show up in File Explorer exactly as before – but they exist only in the cloud. They do not take up any space on your hard drive. When you open a file, it downloads automatically. When you are done, it goes back to being a cloud-only placeholder.

Plain English: You see all your files. They take zero local disk space. They open instantly when you need them.

How to enable Files On-Demand on Windows:

1. Click the OneDrive cloud icon in your system tray (bottom right of taskbar)
2. Click the gear icon → Settings
3. Click the Sync and backup tab
4. Under Files On-Demand, tick Save space and download files as you use them
5. Click OK

How to enable it on Mac:

1. Click the OneDrive icon in the menu bar
2. Click the gear icon → Preferences
3. Click the Files On-Demand tab
4. Select Download files as you use them

Making specific files always available offline:

Right-click any file or folder in File Explorer → Always keep on this device (for files you need available even without internet) or Free up space (to push a local file back to cloud-only status).

For the OneDrive in Microsoft 365 Business, see our OneDrive guide for setup details.

Step 5: Clear Version History on Large Files

Every time you save a document, OneDrive creates a new version. This is incredibly useful – you can go back to any previous version. But those versions count against your storage.

A 200MB video file that has been saved 10 times = 2GB of storage just for version history.

How to check and delete version history:

1. Right-click any file in OneDrive (web browser version)
2. Select Version history
3. You will see every previous version listed with its size
4. Click the three dots (…) next to old versions you no longer need → Delete

For large files specifically: The biggest storage savings from version history come from video files, large presentations, and design files. Audio files, large PDFs, and high-resolution images are also common culprits.

You cannot delete all version history in bulk from the web browser. For bulk version history management across a whole OneDrive, PowerShell scripts are available for IT admins managing multiple accounts.

Step 6: Remove Duplicate Files

Duplicates happen when people download a file, make changes, save a new copy, and forget the original is still in OneDrive. Over time, multiple copies of the same files quietly consume storage.

How to find duplicates:

There is no built-in OneDrive duplicate finder. But you can:

• Search for file names with “copy” or “(1)” in them – these are often duplicates created automatically
• Search for file types you tend to duplicate: *.docx or *.xlsx in the search bar, then sort by name to spot similar filenames side by side
• Use Windows Storage Sense or a third-party duplicate finder like dupeGuru on your locally synced OneDrive folder

Step 7: Check Personal Vault and Shared Files

Personal Vault storage: Files stored in your Personal Vault count toward your OneDrive quota. If you have stored large files there, they contribute to your usage even though you cannot easily see them in your regular file view.

Open Personal Vault, sort by size, and remove anything that does not need to be there.

Shared with me files: Files that others have shared with you do NOT count against your storage – they count against the storage of the person who owns them. You do not need to delete files in “Shared with me” to save space.

For IT Admins: Managing OneDrive Storage Across Your Organisation

If you manage Microsoft 365 for a business and need to oversee storage across multiple users, the Microsoft 365 Admin Centre has the tools you need.

Check Storage Usage Across All Users

1. Go to admin.microsoft.com
2. Click Reports → Usage
3. Select OneDrive → Usage
4. You will see every user, their storage used, and their last activity date

Sort by Storage used to instantly find who is using the most.

Adjust Individual User Storage Limits

By default, every Microsoft 365 user gets 1TB. You can increase or decrease this per user.

1. Go to the SharePoint Admin Centre → admin.microsoft.com/sharepoint
2. Click More features → User profiles → Manage User Profiles
3. Search for the user → Edit My Profile
4. Set a custom storage quota

Or via PowerShell for bulk management:

powershell

Set-SPOSite -Identity “https://yourtenancy-my.sharepoint.com/personal/username” -StorageQuota 512000

(512000 = 500GB in MB)

Identify and Clean Up Inactive Accounts

Users who have left the organisation may have OneDrive accounts full of files that are consuming storage unnecessarily.

In the Admin Centre Reports → OneDrive Usage → filter by Last activity date → export the report to find accounts with no activity in 90+ days.

Before deleting any account, follow your organisation’s data retention policy and ensure any files needed for legal or compliance purposes have been transferred to an active account or SharePoint library.

For the full offboarding process that includes OneDrive data handover, see our identity lifecycle management guide.

Set Storage Limits and Policies

In the SharePoint Admin Centre → Settings → OneDrive, you can:

• Set a default storage limit for all new users
• Set the retention period for a deleted user’s OneDrive (30–3650 days)
• Configure what happens to a user’s OneDrive when their account is deleted

How to Get More OneDrive Storage

If you have freed up space and still need more, here are the options:

For personal accounts:

For business accounts:

All Microsoft 365 Business plans (Basic, Standard, Premium) include 1TB per user. Additional storage beyond 1TB can be added via Microsoft 365 extra cloud storage at approximately AU$3.30/month per 200GB (pricing subject to change – check Microsoft’s site for current rates).

Before buying more storage: Check whether your organisation has unused SharePoint storage. Microsoft 365 tenants also receive pooled SharePoint storage (1TB + 10GB per licensed user). Large files used for collaboration purposes are often better stored in SharePoint team sites rather than individual OneDrive accounts.

Frequently Asked Questions

How do I check my OneDrive storage?

Go to onedrive.live.com, click the gear icon in the top right, then click OneDrive settings → More OneDrive settings → Storage. This shows a bar displaying how much storage is used and how much remains. For Microsoft 365 business accounts, you can also click the gear icon in OneDrive and select OneDrive settings, then scroll to the Storage section. If you are an IT admin, the Microsoft 365 Admin Centre at admin.microsoft.com → Reports → Usage → OneDrive shows storage usage for every user in your organisation.

Why is my OneDrive storage full when I deleted files?

Deleted files go to the OneDrive Recycle Bin – and they still count against your storage quota until you empty the bin. Open OneDrive in your browser, click Recycle Bin in the left sidebar, and click Empty Recycle Bin. This is the most common reason OneDrive storage appears full despite deleting files. The Recycle Bin keeps deleted files for up to 93 days before automatically removing them permanently.

What is Files On-Demand and how does it save storage?

Files On-Demand is a OneDrive feature that lets your files appear in File Explorer as normal without actually taking up space on your hard drive. The files exist in the cloud and only download to your device when you open them. This is especially useful if you have a laptop with a small hard drive – you can have 1TB of OneDrive files visible in File Explorer while using almost zero local disk space. Enable it in OneDrive Settings → Sync and backup → Save space and download files as you use them.

How much OneDrive storage do I get with Microsoft 365?

Microsoft 365 Business Basic, Standard, and Premium all include 1TB of OneDrive storage per user. Microsoft 365 Personal includes 1TB. Microsoft 365 Family includes 1TB per person for up to 6 people. The free personal OneDrive account includes 5GB. Microsoft 365 Basic (personal plan) includes 100GB. For current Australian pricing, see Microsoft’s OneDrive plans page.

Does version history take up OneDrive storage?

Yes. Every saved version of a file counts toward your OneDrive storage quota. If you have a large file (such as a video or a large design file) that has been saved many times, the version history can consume significant storage. Right-click any file in the OneDrive web browser view and select Version history to see all versions and their sizes. You can delete individual old versions to free up storage. Microsoft does not automatically delete version history – it persists until you remove it manually or a retention policy removes it.

What is the difference between OneDrive and SharePoint storage?

OneDrive is personal cloud storage – each user has their own 1TB space for personal work files. SharePoint is team storage – shared space used by departments, project teams, and the whole organisation. Files stored in SharePoint team sites use the organisation’s shared SharePoint storage pool (1TB + 10GB per licensed user), not individual OneDrive quotas. If you have large team project files currently stored in individual OneDrive accounts, moving them to a SharePoint team site frees up individual OneDrive storage while making the files more accessible to the whole team.

Can I get more than 1TB of OneDrive storage?

Yes. Microsoft offers additional OneDrive storage that can be purchased through Microsoft 365. Organisations can add extra cloud storage at additional cost. Individual users on qualifying Microsoft 365 plans can add up to 10TB of additional storage on top of their included 1TB. For current pricing and eligibility, see Microsoft’s additional file storage page. Before purchasing, check whether the issue is actually a need for more storage or simply that the Recycle Bin is full, version history is consuming space, or local sync settings can be optimised.
