Synology NAS file manager
next to your clouds
Connect Synology DSM/File Station and move NAS files between local folders, S3, R2, SFTP, WebDAV, Dropbox, OneDrive, pCloud, and other supported sources.
NAS and cloud work often live in separate tools
Synology is great for local network storage, but moving files from a NAS to object storage, WebDAV, or cloud accounts can involve separate portals, sync packages, or manual downloads.
Use CloudPairs as a NAS-to-cloud bridge
CloudPairs connects to Synology through the supported DSM/File Station flow, then puts NAS folders in the same dual-pane interface as your other storage.
Why CloudPairs for Synology
Synology in either pane
Open Synology beside a local folder or another supported connection, then compare paths before moving files.
Queue-based transfers
Uploads, downloads, folders, and cross-pane copies run through a visible queue with progress, speed, retry, and failure states.
Bulk file operations
Use multi-select, drag and drop, context menus, rename, delete, refresh, new folder, and copy-to-opposite-pane actions where the provider supports them.
Automation-ready
Create scheduled sync tasks with interval, daily, or cron timing, conflict rules, file filters, run history, and retry controls.
Usage visibility
Review transfer history in the audit log and monitor CPU, RAM, network I/O, and transfer activity from the performance dashboard.
Local credential storage
Secrets are stored through the operating system credential store where supported; provider credentials are not needed by the public website to run desktop transfers.
Plan the Synology workflow
Follow the provider-specific connection steps and prerequisites.

Common Synology fixes
DSM login fails
Check host, port, HTTPS setting, username, password, and OTP requirements.
Shared folder missing
Confirm the Synology user has permission to the shared folder in DSM.
Remote access is slow
Review NAS uplink speed, VPN latency, and transfer concurrency for large jobs.
CloudPairs vs alternatives
| Alternative | Limitation |
|---|---|
| Browser dashboards | Good for account administration, but slow for side-by-side file comparison and repeated transfer work. |
| Command-line tools | Powerful for scripted jobs, but harder to audit visually and less approachable for everyday file operations. |
| Single-provider sync apps | Useful for mirroring one account, but not designed for selective transfers across several providers. |
