Copy Folders via Local OneDrive Folder

The most straightforward way to copy folders is by dragging them directly into your local OneDrive sync folder on your computer.

Dragging and dropping files into the local OneDrive directory leverages your computer's built-in file explorer to manage the transfer smoothly.

Open File Explorer and navigate to your external hard drive to find the folder you want to copy.

Open OneDrive folder

Open a new File Explorer window and click on 'OneDrive' in the left-hand navigation pane.

Drag and drop

Click and hold the folder on your external drive, drag it over to the OneDrive window, and release the mouse button to drop it.

Frequently Asked Questions

Does dragging and dropping a folder to OneDrive delete the original copy?

No, dragging and dropping a folder from an external hard drive to your local OneDrive folder copies the files. The original folder and its contents will safely remain on your external hard drive.

Why is OneDrive considered a sync service rather than a backup?

OneDrive synchronizes your files across devices in real-time. If you accidentally delete or overwrite a file on your computer, that change syncs to the cloud immediately, meaning the file is altered everywhere. A true backup keeps independent, historical copies that are isolated from daily syncing.

How do I know if my folder has finished uploading to OneDrive?

You can check the status icons next to your files in the local OneDrive folder. A blue circular arrow indicates that the files are currently syncing, while a solid green circle with a checkmark means the files are fully uploaded and safely stored in the cloud.
