How to Fix OneDrive Conflicting Files and Version Conflicts

What Causes This?

OneDrive conflicting files usually happen when the same file is edited in two places before sync finishes. This is common if you work on the same document across multiple PCs, use OneDrive on the web and desktop at the same time, or lose your internet connection during syncing.

Version conflicts can also appear when OneDrive is stuck, paused, or syncing an older local copy over a newer cloud version. In some cases, Office app sync issues, duplicate folder locations, or a damaged OneDrive cache can trigger repeated conflicted copies.

Common Symptoms

• Files appear with names like filename-PCNAME or Conflicted copy
• You see duplicate versions of the same document in OneDrive folders
• OneDrive shows sync errors or keeps re-uploading the same files
• Changes made on one PC do not match what you see on another
• Office files warn about upload failures or merge conflicts

How to Fix It Manually

1. Check OneDrive sync status first

   • Click the OneDrive cloud icon in the taskbar notification area near the clock.
   • Look for messages like Sync pending, Processing changes, or Can't sync this file.
   • If OneDrive is paused, click Resume syncing.

2. Find the conflicted files

   • Open File Explorer with Windows + E.
   • Go to your OneDrive folder.
   • In the search box at the top right, search for terms like:
     • conflicted
     • your PC name
     • duplicate file names
   • Sort by Date modified so the newest versions are easier to compare.

3. Compare the duplicate versions

   • Open both copies of the file and check which one has the latest edits.
   • If it is a document, spreadsheet, or notes file, save the correct version with a clear name before deleting anything.
   • If both copies contain different changes, merge them manually into one final file.

4. Check the web version in OneDrive online

   • Right-click the OneDrive cloud icon and choose View online, or go to onedrive.live.com.
   • Sign in and locate the same file.
   • Compare the cloud version with the local copies on your PC.
   • Keep the most complete version and rename it clearly if needed.

5. Rename or remove the extra copy

   • In File Explorer, rename the version you want to keep to a normal file name.
   • Move the duplicate or outdated copy to another folder temporarily, or delete it if you are sure it is no longer needed.
   • Empty the Recycle Bin only after confirming the correct version syncs properly.

6. Restart OneDrive

   • Press Ctrl + Shift + Esc to open Task Manager.
   • Under Processes, select Microsoft OneDrive and click End task.
   • Press Windows + R, type:
     • %localappdata%\Microsoft\OneDrive\OneDrive.exe
   • Press Enter to start OneDrive again and let it rescan your files.

7. Reset OneDrive if conflicts keep returning

   • Press Windows + R.
   • Type:
     • %localappdata%\Microsoft\OneDrive\OneDrive.exe /reset
   • Press Enter.
   • Wait a minute. If OneDrive does not reopen automatically, launch it again from the Start menu by searching for OneDrive.
   • After reset, check whether the duplicate conflict files stop appearing.
