QNAP Qsync Client for Windows download

Quick summary

QNAP Qsync Client is a free Windows application that keeps files aligned between your PC and a QNAP NAS. Place items into the special Qsync folder on your computer and the client maintains synchronization with all devices linked to the same NAS, so everyone (and every device) sees the current version of a file.

How synchronization works

Files moved or copied into the Qsync folder are monitored continuously. When a change is detected, the client syncs those changes through the NAS and pushes updates to other connected endpoints. Synchronization runs in the background and supports two-way updates so edits made on any linked device propagate back to the NAS and then outward to the rest of your devices.

Key capabilities

Multiple synchronization configurations to match different workflows (for example, one-way, two-way, or selective sync).
A straightforward drag-and-drop workflow for adding files to the synchronized folder.
Automatic propagation of updates so the most recent version is available on all linked devices.
Suitable for both home users and business environments that need consistent file access.
Helps reduce version confusion and improves access to current documents across platforms.

Quick start checklist

Install the Qsync Client on your Windows PC.
Connect the client to your QNAP NAS account and authorize the device.
Move files into the local Qsync folder or save new files there.
Choose the synchronization mode that fits your needs (e.g., full sync, one-way or selective).
Confirm other devices are linked to the same NAS to receive updates.

Practical tips

Use selective sync if local disk space is limited to avoid downloading every file.
Keep the client up to date to benefit from performance and security improvements.
For large transfers, ensure a stable network connection to prevent incomplete syncs.
Maintain regular backups of critical data in addition to sync, since synchronization is not a substitute for versioned backups.
