FAQ

Frequently Asked Questions

What should I do if SmartScreen blocks the app?

This only happens on the first install. Click 'More info' then 'Run anyway'. After install, the installer automatically registers SmartScreen trust, Defender exclusions, and firewall rules — so reinstalls and updates won't show this warning.

Is it really free? Any hidden costs?

Completely free — no ads, no subscription, no feature limits. You can support development via donation, but it's entirely optional.

Can I use it without an SSH server?

Absolutely. Local drive sync works great on its own. SSH, FTP, and cloud targets can be added whenever needed.

How are conflicts handled in two-way sync?

Choose from: newer wins, source first, target first, keep both, or ask per file. The 'ask' mode shows a dialog for each conflict.

Can I sync to S3 or Google Drive?

Yes. AWS S3 works after pip install boto3. Google Drive, OneDrive, and 30+ clouds work via Rclone. FTP/FTPS and WebDAV work out of the box.

Can HSyncPro be running when I install?

Yes, just run the installer. It automatically terminates any running HSyncPro process before proceeding — no 'please close the app' popup will appear.

Does upgrading preserve my settings?

Yes. Settings in %AppData%\HSyncPro are preserved on upgrade. The installer automatically kills the running app before overwriting — no manual close needed. We also recommend backing up via Profile Export.
