Allway Sync: The Complete Guide to Reliable File Synchronization

Overview

Allway Sync is Windows file‑synchronization software that performs true bi‑directional and n‑way sync between local folders, removable drives, network shares and remote servers (FTP/SFTP/WebDAV). It uses a local database to track modifications and deletions and relies on content-aware algorithms rather than timestamps to reduce data‑loss risk.

Key features

• Bidirectional & n‑way sync: keeps multiple folders identical across devices.
• Change history: local database records file changes and deletions.
• Many source/destination types: local drives, USB, network (SMB), FTP/SFTP, WebDAV, cloud storage connectors.
• Flexible jobs: multiple independent synchronization jobs and profiles.
• Edit‑aware comparison: content-based checks that don’t depend on system clock accuracy.
• No file‑size limits: constrained only by file systems.
• Portable edition: “Allway Sync ‘n’ Go” runs from removable drives.

Pros

• Reliable two‑way synchronization and deletion propagation.
• Supports many file systems and remote locations.
• Granular job settings and difference reports.
• Free for personal/occasional use.

Cons / caveats

• Free tier limits (historically: file‑count limits for personal use).
• Occasional instability reported with some remote protocols.
• UI and advanced configuration can be less intuitive than some alternatives; memory/large‑drive issues reported by some users.

Typical use cases

• Syncing work folders between laptop and desktop or USB drive.
• Mirroring file sets across network shares and removable media.
• Using as a one‑way backup tool when configured accordingly.

Alternatives

• FreeFileSync (open source, popular)
• GoodSync (commercial — note Allway Sync has been associated with GoodSync offers)
• Resilio Sync (peer‑to‑peer)
