Forensic Analysis of Windows Offline Files (CSC) – Analysing Cached Network Files

Windows can store files from network shares locally in what is known as the Client Side Cache (CSC), so that they remain available even without an active network connection. These offline files may contain forensically relevant information about file access, synchronisation processes and user activities.

Enquire without obligation

As part of a professional IT forensic investigation, CSC artefacts are always analysed in conjunction with file system traces, user profiles, registry data and event logs. Only by taking a holistic view is it possible to carry out a robust technical assessment.

This is how the analysis works

Once a forensic image has been created, any existing CSC artefacts are identified, analysed and correlated with other digital traces in terms of both timing and technical characteristics.

Why are offline files important?

Even if files were stored on a Server, local offline copies and metadata can provide valuable insights into their use.
