How Duplicates Sneak In and Disrupt Your OneDrive
Duplicate files in OneDrive are a pervasive issue, primarily stemming from synchronization conflicts and user actions.
Common Causes of Duplicates
| Cause | Description | Example of Duplicate File Name |
|---|---|---|
| Conflicting File Versions | Occurs when the same file is edited on multiple devices or when sync delays cause OneDrive to preserve both copies to avoid data loss. |
Filename (!).docx or Filename - LaptopName.docx |
| Syncing Errors or Delays | Network interruptions or incomplete uploads prevent OneDrive from detecting existing files, resulting in duplicate copies of the files. | Filename - Copy.pdf |
| Manual Uploads or Copying | Uploading or copying an existing file manually within OneDrive folders creates redundant versions. | Copy of Filename.jpg |
| Multiple Account Usage | Saving identical files across personal and business OneDrive folders or using overlapping sync directories. |
Filename - Personal.docx Filename - Business.docx |
| Third-Party App Integrations | Backup or synchronization apps (e.g., photo sync tools) may unintentionally generate duplicate backups. | Filename_backup{1}.png |

Remove Duplicate in Personal or Business Account
Now, let’s begin the step-by-step process of using SysInfo OneDrive Duplicate Finder and Remover to easily locate and delete duplicate files from your OneDrive.
Step 01: Download and Run OneDrive Duplicate Finder and Remover
Download the SysInfo OneDrive Duplicate Finder and Remover from the official SysInfoTools website. Once downloaded, open the setup file and follow the simple on-screen instructions to install it on your system.
After installation, launch the tool, ideally by choosing “Run as Administrator” for best performance. The software will open with a clean, intuitive interface, ready to help you connect your OneDrive account and begin scanning for duplicates.
Most important: This tool is compatible only with cloud-based domains. Domains linked to on-premise Exchange or local servers are not supported.
Step 02: Launch the Tool
Once the installation is complete, open the SysInfo OneDrive Duplicate Finder and Remover application. On the initial screen, you’ll see three main buttons: Launch, Open, and Close.
Step 03: Select OneDrive Account and Sign In
Next, choose your OneDrive account type and sign in using valid Microsoft credentials. The tool provides three secure login options:
1. Personal Account: Use this option if you’re logging in with your individual Microsoft account (e.g., Outlook, Hotmail, etc).
2. Business Account: Select this for Microsoft 365 Business or Enterprise accounts used within an organization.
3. Business Account with Impersonation Access: Designed for admins who need to scan and manage duplicate files across multiple employee or shared accounts.
Important Note on Process Flow The duplicate removal process for OneDrive varies slightly depending on the type of account you use. The steps for Personal and Business accounts differ from those that involve Impersonation Access. To ensure clarity and better understanding, we’ve first outlined the complete process for Personal and Business Accounts. After that, we’ll cover the Impersonation Access method separately, highlighting the additional steps and controls available for administrators managing multiple user accounts.
Step 04: Scan All Folders from OneDrive Storage
After signing in, the tool displays a detailed OneDrive Storage Summary. This dashboard includes a pie chart showing your used and available storage space, along with key account details such as account name, total storage, used space, and last updated timestamp. Click Scan All Folders to proceed.
You’ll also find two main action buttons on this screen:
How Auto Delete Works?
The Auto Delete feature is designed for maximum efficiency; it works nearly 50% faster than manual deletion methods. By automatically identifying and removing duplicates based on predefined rules, it saves both time and effort while ensuring precise, error-free cleanup of your OneDrive storage.
After selecting Auto Delete, a new window will appear with four cleanup options. Choose your preferred option and click OK to confirm.
A confirmation message will appear; click OK again to proceed.
A progress window will then display the ongoing duplicate removal process.
Once completed, you’ll see a detailed report showing:
User ID
Duplicate Count
Duplicate Size
Step 05: Scan All Folders from OneDrive Storage
After connecting your OneDrive account, the tool will display all your files and folders in a detailed table that includes the file or folder name, size, and date modified. You can use the built-in search bar to quickly locate specific files or folders you want to check.
Once you’ve selected the desired files or directories, click on the Find Duplicate Files button to start scanning. The tool will then analyze your OneDrive storage and present a list of duplicate files, allowing you to review, manage, or remove them as needed.
After the scanning process finishes, a pop-up message will appear saying “ Scan Completed Successfully. ” It will display the total number of duplicate files detected along with the number of duplicate groups found in your OneDrive.
Step 06: View Group-Wise Sorted List of Duplicates
This wizard displays the scan results, showing all the duplicate files detected in your OneDrive, neatly organized into groups. Each group represents a set of identical or similar files found during the scan.
Here’s what you’ll see and can do in this window:
Action Buttons:
Note: Each group contains identical duplicate files of the same type, making it easy to review and remove them accurately.
Step 07: Select Duplicate Files
In this step, choose the duplicate files you want to remove. You can either select them manually or use the Select Duplicates option, which offers three quick choices:
Step 08: Delete Duplicates
Once you’ve selected the duplicate files, it’s time to delete them. The SysInfo OneDrive Duplicate Finder and Remover provides two deletion options:
After selecting either Delete Permanently or Move to Bin, a confirmation alert will appear to ensure you want to proceed with the deletion. Review your choice, then click OK to continue. The tool will then begin removing the selected duplicate files based on your chosen option.
Once you confirm the deletion, a progress window appears on the screen to indicate that the duplicate removal process has started. This window displays real-time updates, showing which file is currently being processed, for example, “Processing file: image23.jpg”.
Important Note: Always exercise caution when deleting files. While the Recycle Bin option provides safety, permanent deletion cannot be undone. Review all selections carefully before proceeding with any deletion operation.
Step 09:View and Generate Report
After the deletion process is completed, the tool displays a detailed summary report of all removed duplicate files. This report includes the total number of deleted files, the total storage space freed, and a table listing each deleted file’s name and file path.
For record-keeping or analysis, click the Generate Report button to download the complete report in CSV format. This helps you maintain a clear record of the cleanup process and track your OneDrive storage optimization.
Impersonation Access Method
The steps up to the login stage remain the same. However, after signing in with your Business Account with Impersonation Access, the tool will automatically fetch and display all user accounts associated with your organization. Now, we will proceed with the further steps after logging in to manage and remove duplicate files from the user accounts.
Step 04: Select Users from List of Users
After logging in with Impersonation Access, the tool displays a List of Users window that includes all user accounts associated with your organization. Each entry provides key details to help administrators choose which accounts to scan for duplicates.
Here’s what you’ll see on this screen:
| Delete Permanently | Move to Bin |
|---|---|
|
Step 5: Click Delete Permanently Click Delete Permanently to remove duplicate files from the selected user's OneDrive account. A confirmation alert will appear asking if you want to proceed with the deletion. Click OK to confirm. 
After clicking OK, a process window will appear showing the status of the ongoing deletion process. 
|
Step 5: Click Move to Bin If you prefer a safer cleanup option, click Move to Bin instead. A confirmation alert will pop up; click OK to continue. 
After confirming the action, a process window will appear showing the status of files being moved to the recycle bin. 
|
| Step 6: Generate Report | Step 6: Generate Report |
Once the deletion is complete, a summary table will display details such as
User ID, Duplicate Count, and Duplicate Size.
Click Generate Report to download a CSV file containing the complete report of deleted files.
|
After the move-to-bin process finishes, the software will show a summary table with
User ID, Duplicate Count, and Duplicate Size.
Click Generate Report to save a CSV file containing the details of all duplicates moved to the bin.

Issues and Troubleshoots
| Authentication Failures | Slow Scanning |
|---|---|
|
If you encounter login or authentication errors, ensure that your Microsoft account credentials are entered correctly.
→ Confirm that the login email and password are valid for the connected OneDrive account. → Verify that the tool has been granted the necessary permissions to access OneDrive storage. → For Business or Enterprise users, ensure that admin consent is provided if required by your organization’s policy. Tip: Reauthenticate through the Microsoft Sign-in portal if the token expires or access is denied. |
Scanning speed may vary depending on the number and size of files stored in your OneDrive account.
→ Large data volumes or nested folder structures may increase scanning time. → Maintain a stable and high-speed internet connection to avoid timeouts. → Avoid running multiple OneDrive operations simultaneously while scanning. Tip: For faster performance, scan specific folders instead of the entire drive. |
| Network Issues | Permission Errors |
|
If the software displays connection or timeout errors, it is likely due to unstable or restricted network access.
→ Ensure your device has an active and reliable internet connection. → Disable any VPN or proxy that may block access to OneDrive servers. → Check that firewall or antivirus settings are not restricting the application’s communication with Microsoft cloud services. Tip: Restart your router or reconnect to a different network if connection issues persist. |
Certain operations, especially for Business or Admin accounts, require specific access rights.
→ Make sure you have admin privileges if using Impersonation Login or scanning shared drives. → Verify that the connected account has edit permissions on the selected OneDrive directories. → If using a corporate domain, confirm that the account is cloud-based (not on-premise), as on-premise servers are not supported. Tip: Contact your IT administrator to verify permission levels if the tool is unable to access specific folders. |
