Synchronize selected files and folders between compatible devices with direction, conflict and deletion controls.

## Keep selected files aligned between devices

Laplink Sync synchronizes selected files and folders between compatible computers and mobile devices. Use it to exchange working documents or copy photos and videos as part of a repeatable file-management routine.

Choose a small set of folders with a clear purpose before expanding the setup. Keep the originals available while you confirm where the files arrive and how later changes are handled.

## Choose folder pairs and the transfer direction

The documented workflow pairs a folder on one device with a folder on another. One-way and two-way synchronization determine how files travel between those locations, and multiple folder pairs can be selected.

Give each pair a recognizable purpose, such as work documents or camera pictures. Check both paths and the direction before starting, especially when the devices use different folder names for similar content.

## Review conflicts before replacing a file

UltraSync tracks file changes, renames and deletions. When versions conflict, the workflow lets you choose which copy to keep or exclude a file pair rather than silently assuming every change has the same priority.

If a document was edited on both devices, compare the contents before choosing a direction. Preserve both versions separately when they contain different useful changes; synchronization should not be treated as automatic document merging.

## Decide how deletions should propagate

The guide describes controls for allowing file deletions during synchronization. Their scope differs by client, so inspect the setting in the device that initiates the sync rather than assuming one choice applies everywhere.

This matters when copying photos off a phone and then removing the phone copy. Test that exact sequence with expendable sample files before using it for a large collection, and keep another copy outside the synchronized folder pair.

## Account for differences between device clients

Laplink documents clients for Windows, Mac, Android and iOS, with wireless and wired-network connection workflows. The iOS workflow in the guide is limited to pictures and videos rather than arbitrary documents or folders.

Check that the client you intend to use is available and usable on your actual device before planning a workflow around it. The documentation spans older client releases, so it should not be read as a promise of identical behavior across all current devices.

## Use synchronization alongside independent backups

Synchronization keeps selected locations aligned. It does not by itself provide a protected history of every earlier version, and a mistaken replacement or propagated deletion can affect more than one copy.

Keep important data backed up outside the sync relationship. Our [file-backup guide](https://find-your-software.com/solutions/how-to-backup-files.html) explains independent copies, while [Laplink DiskImage](https://find-your-software.com/laplink/diskimage/) covers a separate imaging and recovery workflow.

## Choose synchronization or migration by the task

For repeated file exchange, review the folder-pair and conflict workflow described here. For moving selected files, settings and profiles into a new Windows setup, see [Laplink PCmover Express](https://find-your-software.com/laplink/pcmover-express/).

## Laplink Sync FAQ

### What is Laplink Sync used for?

It synchronizes selected files and folders between compatible devices. Choose the folder pairs and transfer direction around the files you want to keep aligned.

### Can I choose one-way or two-way synchronization?

Yes. The documented workflow provides direction controls for folder pairs. Review both paths and the selected direction before starting.

### What happens when a file has changed on both devices?

The workflow identifies a conflict and lets you choose which version to keep or exclude the pair. Compare important changes first; it is not automatic merging of document contents.

### Will deleting a synchronized file remove the other copy?

That depends on the deletion setting and client. Check the controls on the initiating device and test the behavior before using it with important files.

### Can I synchronize arbitrary documents with the iOS client?

The documented iOS workflow supports pictures and videos, not general document synchronization. Check the available client and its actual behavior before planning a mobile workflow.

### Does synchronization replace a backup?

No. A synchronized copy may also receive an unwanted replacement or deletion. Keep an independent backup outside the synchronized locations.

### Does Laplink Sync move installed applications to another PC?

Its role is file and folder synchronization. Do not treat it as an application-migration tool or a complete system-image recovery workflow.
