SyncToy is a free sync tool developed by Microsoft that synchronizes files and folders between different locations or devices, but some users experience issues with it not copying all files.
The user has experienced issues with SyncToy not syncing all files from the left folder to the right folder, especially when using the ECHO setting. Additionally, it fails to detect and replicate "moves" and "deletions" in the left folder, resulting in incomplete syncing and not deleting folders as expected. This behavior contradicts SyncToy's stated functionality.
Some users are experiencing issues with SyncToy, including not selecting OneDrive folders during synchronizing, and encountering errors such as "Failed to create folder pair" and "Failed to create the provider". Additionally, SyncToy is unable to sync files and folders that are not WebDAV, like those found in Windows Mobile folders.
I'm happy to help! However, I don't see any specific problems mentioned.
Fix 1: Create another folder pair
If SyncToy isn't syncing all files, check if there are subfolders in the left folder. If so, create a separate folder pair for those subfolders to resolve the issue.
Fix 2: Repair using Microsoft Sync Framework
If SyncToy fails to create folder pairs or encounters issues with the provider, try the following: go to the Add/Remove programs section in Control Panel, find the entry for Microsoft Sync Framework 2.0 Provider Services, click on it, select Repair, and then re-run SyncToy. This should resolve the problem.
Fix 3: Try SyncToy alternative
If you're experiencing issues with SyncToy or seeking more advanced features for file and folder syncing, consider using a SyncToy alternative, such as Qiling Disk Master Standard, which offers a powerful Sync feature that can handle subfolders and provide a more comprehensive syncing experience.
You can sync files/folders from one drive to another in Daily, Weekly, or Monthly modes, as well as sync from a local drive to a network location or cloud drive, all for free. You can download and try it.
Install and launch Qiling Disk Master on your computer. If desired, connect an external storage device to sync files to it.
1. In Qiling Disk Master, go to Sync and select Basic Sync, which is a one-way sync mode.
2. To sync a folder, click on the "Folder" option and select the folder you want to sync.
3. Click the second box to add the destination location.
4. Click Options to set email notifications if desired, and then click Schedule to select the frequency of the report, such as Daily, Weekly, or Monthly.
5. You can proceed to sync files right now or at the next scheduled time.
✎Tips:
If you're experiencing issues with SyncToy not copying all files, try removing any subfolders from the left folder. If that doesn't work, consider repairing SyncToy and trying again. However, a more permanent solution may be to find an alternative syncing tool that works across all versions of Windows, including 10, 8, and 7.
Qiling Disk Master offers features beyond Sync, including Backup options like System Backup, File Backup, and Disk Backup, as well as Cloning features such as System Clone, Disk Clone, and Partition/Volume Clone.
