Where Does OneDrive Store Partial or Incomplete Downloads?
Product
OneDrive
Device & OS
not provided
Scenario
Attempting to locate and manage storage space consumed by incomplete or stuck OneDrive file downloads.
Observed behavior
Partially downloaded OneDrive files are temporarily consuming local disk space even though the files are set to appear as online-only.
Before you start

Before attempting to delete any temporary or partial files, ensure your device has a stable internet connection to allow OneDrive the opportunity to finish the synchronization process.

Solution 1Recommended

Locate Partial Sync Files in the Desktop OneDrive Folder

Check the local OneDrive sync folder if the partial download occurred via the desktop synchronization application.

When using the desktop application, files being synchronized are held directly in your local OneDrive folder. Incomplete downloads will remain here until the sync process finishes.

1
Open File Explorer

Press the Windows Key + E on your keyboard to open File Explorer.

2
Navigate to the OneDrive Folder

Click on the 'OneDrive' folder icon located in the left-hand navigation pane to open your local sync directory.

3
Identify Syncing Files

Look for files that have a blue circular arrows icon in the status column, or check for files with temporary extensions indicating an incomplete download state.

Locate Partial Sync Files in the Desktop OneDrive Folder
Do Not Delete Syncing Files: Avoid deleting these files manually until synchronization is complete and the cloud copy is confirmed, as this could lead to data loss or corruption.

Frequently Asked Questions

Can I manually back up the OneDrive temporary cache data?

Normally, the OneDrive cache cannot be easily backed up or restored manually. Extracting usable data from the cache typically requires specialist software, so it is highly recommended to wait for the sync to complete and back up the actual finished files.

Why are my online-only files taking up local disk space?

When an online-only file is accessed or actively downloading, OneDrive temporarily caches the file data on your local hard drive to process the request. This temporarily consumes local disk space until the download finishes or until Windows automatically clears the cache.

How do I safely stop a stuck OneDrive download?

To safely stop a stuck download in the desktop app, pause the synchronization process. Click the OneDrive icon in your system tray, select the Help & Settings gear icon, and choose 'Pause syncing' for 2 hours. After pausing, you can safely restart your computer or resume syncing to clear the error.
