SyncToy for Windows 11: What to Use Now

SyncToy was a simple Microsoft folder sync utility, but it is no longer actively maintained. On Windows 11, users should consider compatibility and data safety.

Understand the problem

Folder sync is not the same as backup. If a file is deleted or corrupted on one side, sync may copy that change to the other side.

• Confirm the exact disk, partition, file system, Windows version, boot mode, or sync setting before making changes.
• Back up or recover important files before wiping, formatting, converting, cloning, reinstalling, or repairing Windows.
• For boot and update tasks, prepare recovery media and check BIOS or UEFI settings before deeper repair.

Use Windows built-in tools

Plan sync direction before using any tool.

1. Identify source and destination folders.
2. Decide whether you need one-way backup, two-way sync, or mirror sync.
3. Test with a small folder first.
4. Keep a separate backup for important files.
5. Check sync logs after each run.

Function. Back up important files first

Step 1. Connect an external drive or choose a safe network location with enough free space for folders you plan to sync.

Step 2. Open Qiling Disk Master and choose File Backup. This protects files before cleanup, partition changes, repair, or system updates.

Step 3. In the tree control, select the files and folders that must be protected. Keep an independent backup before testing any two-way or mirror sync workflow

Step 4. Choose a destination that is not affected by the operation, such as another disk, external drive, NAS, or shared folder.

Step 5. Review the source and destination, then click Proceed. Wait for the backup to finish before continuing.

Check the result

After sync, compare file counts and modified dates. Confirm deleted files were not mirrored unexpectedly.
