EnCase’s Evidence Files (.E01) are similar to other documents in that they have structured internal metadata describing the evidence item, examiner, date acquired, etc… EWF MetaEditor allows you to edit these properties in order to fix typos, rename incorrect/mislabeled evidence items, and add missing information.

This tool include several features to work with Encase file and Expert Witness Disk Image Format (EWF):

• Remove passwords on EnCase v6 and earlier files
• Find out if compression (and what level) was used
• Change EWF/E01 metadata
• Requirements: Microsoft .NET Framework v4.0
• Free for both personal and commercial use
