How to Fix OneDrive "Not Enough Space" Error When Uploading Large ZIP Files

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Attempting to upload a large ZIP file to Microsoft OneDrive cloud storage.
Observed behavior: OneDrive displays a "not enough space" error and halts the upload, even though adequate storage space is available on the account.

Before you start

Verify the exact file size of your ZIP file and ensure you have a stable internet connection before beginning the troubleshooting process.

Solution 1Recommended

Verify Account Storage and Upload via File Explorer

Confirming your online storage capacity and using the local File Explorer integration is the most reliable way to upload large files without browser timeouts or false storage errors.

Web browsers can sometimes struggle with large uploads or cache incorrect account details. Using the desktop File Explorer circumvents these limitations by syncing the file in the background.

Check online storage

Navigate to https://www.onedrive.com in your web browser and sign in. Check the storage metric in the bottom-left corner to confirm you are in the correct account and have enough free space.

Open local OneDrive folder

Open File Explorer on your computer and click on the 'OneDrive' folder located in the left-hand navigation pane.

Move the ZIP file

Drag and drop the large ZIP file into the local OneDrive folder. Leave your computer powered on and connected to the internet while the client syncs the file to the cloud.

Verify Account Storage and Upload via File Explorer

Upload Complete: Once the file shows a solid green checkmark icon in File Explorer, the upload is completely synced to the cloud.

Solution 2

Reset the OneDrive Client

If OneDrive is out of sync with the cloud server and misreporting available storage, resetting the desktop client will clear its cache and force a fresh synchronization.

Frequently Asked Questions

What is the maximum file size I can upload to OneDrive?

OneDrive allows you to upload individual files up to 250 GB in size. However, for extremely large ZIP files, uploading via the desktop client (File Explorer) is highly recommended over using a web browser for better stability.

Why does OneDrive say my storage is full when it isn't?

This usually happens if you are logged into a different Microsoft account on your desktop client than on your web browser, or if the local OneDrive cache has become corrupted and requires a reset using the '/reset' command.

Can I split my large ZIP file into smaller parts to upload?

Yes. If you continue to face upload errors, you can use archiving software like WinRAR or 7-Zip to split your large ZIP file into smaller, multi-part volumes (e.g., 5GB each) which can be synced to the cloud much more easily.
