How do I remove OneDrive and get my local Documents folder back?

First, check both Documents folders and make sure you know where your files are. Don't delete the OneDrive folder yet. Copy anything you need into your local Documents folder, and keep a backup until you've checked that the copies open.

Then right-click Documents in File Explorer, open Properties and look for the Location tab. Use Move to select the local Documents folder, usually under C:\Users\your account\Documents. Follow the prompts and check the result before removing any leftovers. You can repeat this for other folders that still point into OneDrive.

If the Documents location is already correct, the Quick Access entry might just be an old pin. Try right-clicking it and unpinning it, then find your local Documents folder and pin that instead. Unpinning removes the shortcut, not the folder or its files.

Since OneDrive is already uninstalled, another option is to reinstall it temporarily, turn off folder backup and syncing in its settings, and then uninstall it again. Check where your files ended up before removing anything left in the OneDrive folder. Uninstalling the app doesn't necessarily remove its folders or change every folder location.
