Czkawka on Network Drives and NAS Shares

A mounted network share may be scanned when accessible as a filesystem path, but performance and permissions depend on the network and server.

Short answer: Can I scan NAS files with Czkawka on Windows?

A mounted network share may be scanned when accessible as a filesystem path, but performance and permissions depend on the network and server.

What to know before you begin

A mounted network share may be scanned when accessible as a filesystem path, but performance and permissions depend on the network and server. The project offers several scanning modes and the current version may place controls differently in Krokiet versus the older GTK GUI. Follow the meaning of the option you see, not just a screenshot from a different release.

For Windows, verify that your chosen folder is accessible and that the correct graphical frontend is running. The recommended approach starts with a small test set, especially when an action could rename, move, delete or link files.

Step-by-step: Can I scan NAS files with Czkawka on Windows?

  1. Map the share to a drive letter or accessible path.
  2. Check read permissions and available throughput.
  3. Scan a limited folder first and inspect the results.
  4. Perform deletions using the server's snapshot or backup protections.

Important limitation

Before changing files: Remote file permissions, latency and concurrent edits can change results.

How to verify the result

Verify server-side snapshots and scan results against a local test set. A scan's estimated savings or the presence of a matching group does not by itself establish which copy should be discarded.

If the procedure does not match your screen, inspect the project's own FAQ and troubleshooting notes and identify the exact release and frontend first.
