What Is SyncToy?

File sync is the process of copying files from one location to another. It can bring you a big convenience for working on same files in different PCs.

SyncToy is a file sync software developed by Microsoft. It is free and it offers a graphical user interface to help users synchronize local or network files/folders. What's more, it keeps track of renames to files to ensure the changed folders can be synchronized. This free tool can save the sync data in multiple locations and devices. 

Besides, it is able to update the information of synced files and mark them as duplicated, discontinued, or spam. However, SyncToy has some shortages:

  • SyncToy can’t synchronize those files not using WebDAV, such as “Windows Mobile” files or folders. If you want to synchronize removable device files or folders, then SyncToy can’t help.

  • SyncToy doesn't support scheduled sync tasks. If you want to run SyncToy automatically, you should resort to Task Scheduler.

Well, you may ask, "What if I need to sync files and folders in removable devices, what can I do?", "Why is SyncToy not available on Windows 10?", "Is there any SyncToy alternative?"

Best Free SyncToy Alternative for All the Windows PCs

As we mentioned above, SyncToy is a great tool designed by Microsoft. It has strong features to synchronize files and folders to different locations and devices, but it also has shortages as listed above. Besides, its last version of SyncToy was discontinued in January of 2021 and does not support on Windows 11.

Fortunately, you can find the best free SyncToy alternative, which is more powerful than SyncToy to make up for the deficiencies and offers workarounds to SyncToy errors like SyncToy not copying all files.

Speaking of synchronization software, here we highly recommend AOMEI Backupper Standard, which has strong functions in regard to file sync.

Various sync locations: it can not only synchronize folders to local disks or devices but also other computers through network share or NAS, cloud drives, etc.
Schedule sync: it allows you to set a sync task to run automatically and periodically. You can choose from "Daily", "Weekly" or "Monthly".
Wide compatibility: it runs well on Windows 11/10/8/7/Vista/XP. For server users, try SyncToy server alternative - AOMEI Backupper Server

As you can see, AOMEI Backupper should be the best alternative to Microsoft SyncToy.

How to Use SyncToy Alternative Freeware to Sync Files 

AOMEI Backupper Standard's sync feature can help you synchronize files in a simple way. It is better than SyncToy not only because of the strong functions but also the easy operations. It only needs several clicks to create a sync task. Before you do, you must know:

  • It is not allowed to synchronize a single file of more than 4 GB to a FAT/FAT32 drive due to the limitation of the file system.

  • It is not allowed to synchronize files or folders to CD/DVD/Blue-Ray.

  • The Standard edition only supports one-way file sync with Basic Sync feature. To enjoy more advanced sync modes like Mirror Sync, Two-Way Sync and Real-Time Sync, you need to upgrade to higher editions.
