Sync Client Keeps Downloading Deleted Files: Root Cause and Fix

When you delete files from a SharePoint or OneDrive library, the OneDrive sync client may re-download them back to your computer. This creates confusion and wastes bandwidth. The root cause is a mismatch between the sync client’s local cache and the actual file version stored in the cloud. This article explains why the sync client re-downloads deleted files and provides a step-by-step fix to stop it.

Why the Sync Client Re-Downloads Deleted Files

The OneDrive sync client uses a local cache to track which files are present on your computer and which are in the cloud. When you delete a file from the cloud library using another device or the web interface, the sync client may not immediately detect that deletion as a removal. Instead, the sync client compares its local cache to the cloud file list and sees the deleted file as a new addition that must be downloaded.

Sync Token Mismatch

The sync client stores a sync token for each library. This token is a snapshot of the current file and folder structure. When the cloud library changes, the sync client requests a new token. If the token update fails or is delayed, the sync client sees the deleted file as still present in the cloud and downloads it again. This mismatch is the most common cause of the re-download behavior.

File Version History Confusion

SharePoint and OneDrive keep version history for every file. When you delete a file, its version history remains in the recycle bin for a period. The sync client may interpret the version history as a live file and attempt to download the most recent version. This is especially true if the sync client scans the library metadata before the deletion is fully processed.

Recycle Bin Not Cleared

Files you delete from a SharePoint library go to the site recycle bin first. The sync client may still see the file in the recycle bin and treat it as a recoverable item. If the sync client is configured to sync all library contents, it may attempt to download the file again because the recycle bin entry appears as a valid file path.

Steps to Stop the Sync Client from Re-Downloading Deleted Files

1. Update the OneDrive sync client
   Open OneDrive settings by right-clicking the cloud icon in the system tray and selecting Settings. Go to the About tab and check the version number. If the version is earlier than 22.022, download the latest version from the Microsoft OneDrive download page. Restart your computer after the update.
2. Clear the sync cache
   Close OneDrive completely. Press Ctrl+Shift+Escape to open Task Manager. End all OneDrive processes. Press Win+R, type %localappdata%\Microsoft\OneDrive\settings\Business1 and press Enter. Delete all files and folders inside this folder. Restart OneDrive. This forces the sync client to rebuild its cache and request a new sync token from the cloud.
3. Empty the SharePoint recycle bin
   Open the SharePoint site where the files were deleted. Select the gear icon and choose Site contents. Click Recycle bin on the left navigation. Select all items and click Delete. Confirm the deletion. This removes the file references that may confuse the sync client.
4. Disable and re-enable sync for the library
   In OneDrive settings, go to the Account tab. Click Stop sync next to the library that has the issue. Wait 30 seconds. Click Add account or Sync again for that library. This reinitializes the sync relationship and discards the old sync token.
5. Reset OneDrive from the command line
   Press Win+R, type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press Enter. Wait for the reset to complete. Restart OneDrive. This clears all cached sync data and forces a full re-sync with the cloud.

If the Sync Client Still Re-Downloads Deleted Files

OneDrive Sync Client Shows Files as Conflict Versions

If the re-downloaded files appear with a conflict suffix like (user’s conflicted copy), the issue is caused by a sync token mismatch that was partially resolved. Open the file in the cloud library and delete the conflict version. Then clear the sync cache again using the steps above.

Deleted Files Reappear After Clearing Cache

This indicates that the file still exists in a different location within the same library, such as a subfolder that is synced separately. Use the SharePoint web interface to search for the file name across the entire library. If the file is found, delete it from that location. Then empty the recycle bin.

Sync Client Downloads Old File Versions

If the sync client downloads an older version of a file that you already deleted, the version history is the cause. Go to the library settings in SharePoint and set the version history limit to 0 or 1. This prevents the sync client from seeing old versions as separate files.

Sync Client Versions and Re-Download Behavior

Version	Re-download behavior	Fix available
22.021 and older	Frequent re-download of deleted files	Update to 22.022 or newer
22.022 to 23.001	Occasional re-download if cache is stale	Clear cache or reset OneDrive
23.002 and newer	Rare re-download; token sync improved	Clear cache only if issue persists

The sync client re-downloading deleted files is almost always caused by a stale sync token or uncleared recycle bin. Updating the sync client to the latest version and clearing the cache resolves the problem in most cases. If the issue continues, verify that the file is not stored in a different location within the same library and that version history is trimmed. After applying these fixes, the sync client will accurately reflect the current state of your cloud library.
