Reliable folder synchronization made simple

SyncToy 64-bit, developed by Microsoft, is a free folder sync tool designed to keep two file locations consistent. It supports a few clear synchronization modes, which helps match different habits, from one-way copying to true mirroring. The interface stays straightforward and focused, which works well for people who want dependable syncing across local folders or network locations without a lot of extra features.

SyncToy 64-bit lets you create folder pairs using a left folder and a right folder, then choose how changes move between them. Synchronize updates both sides with newer changes, Echo makes the right side mirror the left including deletions, and Contribute copies newer files without deleting anything on the right. That range is a real strength, since it can support both cautious copying and strict mirroring depending on your goal.

Flexible sync options tailored to your workflow

A preview step shows proposed changes before anything is applied, which adds control and reduces unwanted surprises. Filters can exclude certain files or subfolders, and logs keep a record of what happened after a run. These details make the tool feel reliable for routine syncing, even though the workflow stays manual rather than always-on.

Simple setup with practical automation options

A wizard-style setup helps users define folder pairs and pick a sync mode without digging through technical menus. The program focuses on syncing folders you can access, including network shares when permissions are set correctly. That makes it a practical option for basic home or small office workflows that rely on shared folders rather than cloud apps.

SyncToy also includes a command-line component that supports scheduled or scripted runs through standard system scheduling tools. That option adds flexibility for repetitive tasks, although it still takes setup effort and does not deliver the kind of seamless real-time syncing found in newer file synchronization software.

Clear limits for modern workflows

SyncToy 64-bit handles common synchronization jobs efficiently and stays lightweight during typical runs, which suits large folders and everyday file updates. The trade-off is that it lacks modern conveniences, such as real-time syncing and built-in cloud service integration. Users who want set-and-forget behavior can find the manual, run-when-needed approach less convenient.

The feature set also stays focused on synchronization rather than true backup management. There is no built-in version history or recovery-focused tooling beyond keeping two folders aligned. That limitation matters for anyone who wants rollback options or deeper reporting instead of straightforward folder mirroring.

Focused and effective for basic folder syncing

SyncToy 64-bit delivers a clear, dependable way to sync folders using flexible modes, previews, filters, and logging. Its simple setup and optional command-line runs fit users who want control over what changes and when. The manual nature and lack of modern cloud and real-time features define its scope, making it best for straightforward folder syncing rather than full backup workflows.
