Question details

The user is attempting to upload a large batch of files to the OneDrive website, but the process halts at duplicate filenames without offering a global option to skip them.

How to Skip Duplicate Files During a OneDrive Web Upload

Product: OneDrive
Device & OS: not provided
Scenario: Uploading a bulk collection of approximately 1,000 photos to the OneDrive web interface where some files already exist in the destination.
Observed behavior: The web upload pauses when it detects a duplicate filename and requires the user to manually select 'Replace' or 'Keep both' for each individual file, lacking a 'Skip All' function.

Before you start

Before attempting bulk uploads or resolving file conflicts, ensure you have enough stable internet bandwidth and a local backup of your photos to prevent accidental overwriting.

Solution 1Recommended

Use the OneDrive Desktop Sync Client

Using the desktop application allows you to leverage your operating system's native file explorer, which provides a global 'Skip' option for duplicate files.

The OneDrive web interface is designed for simpler tasks and currently lacks advanced conflict resolution like a 'Skip All' button. By switching to the desktop sync client, you can manage bulk uploads much more efficiently.

Install OneDrive Desktop

Download and install the OneDrive desktop application on your computer if it is not already set up. Sign in with your Microsoft account.

Locate the Local OneDrive Folder

Open Windows File Explorer (or macOS Finder) and navigate to the newly created local OneDrive folder.

Transfer the Files

Copy your large batch of photos from their current location and paste them into the desired folder within the local OneDrive directory.

Skip Duplicates Globally

When the operating system prompts you that files with the same names already exist in the destination, check the box to apply the action to all conflicts, and select 'Skip these files'.

Automatic Synchronization: Once the files are moved to the local folder and duplicates are skipped, the OneDrive app will automatically sync only the new files to the cloud in the background.

Solution 2

Upload in Smaller Batches to Separate Folders

If you must use the web interface, organizing your files into new folders prevents duplicate conflicts during the upload process.

Frequently Asked Questions

Why doesn't the OneDrive web interface have a 'Skip All' button?

The web version of OneDrive is built for basic file management and currently lacks the advanced batch conflict resolution found in local operating systems. It forces manual decisions on duplicates to prevent accidental data loss.

If I choose 'Keep both' during the upload, what happens to my storage?

Selecting 'Keep both' will append a number to the newly uploaded file's name and save it alongside the original. This means both files are kept, which will consume double the storage space for those specific items.

Can I bypass the prompt by renaming files before uploading?

Yes. If you use a batch renaming tool on your computer to add a unique prefix or suffix to your files before uploading them to the OneDrive website, they will not be recognized as duplicates, and the upload will proceed without interruption.
