Can Proof Finder directly ingest forensic images?

Proof Finder can directly ingest some forensic images should you be presented with this type of data.

Directly ingesting forensic images allows Proof Finder to process the source data without interference from the operating system or the file system security.

  • EnCase: E01, E02, E03, etc... - Both single E01 files and segmented.
  • EnCase: L01, L02, L03, etc... - EnCase Logical Volumes.
  • DD Images: DD- Single file dd images. dd.01, dd.02, dd.03, etc...
  • Access Data: AD1 logical images

Note: Nuix strongly recommends processing logical images over physical images.

How do I add segmented EnCase images?

Create a directory that contains all of the segments associated with a given image and ensure they are under approximately 8 GB to allow for compression. 

What file systems are supported by Proof Finder?

Only images of the following file systems will be processed by Proof Finder.

  • Windows: FAT32, NTFS
  • Linux: EXT2, EXT3, EXT4
  • Mac OS X: HFS+, HFSX
  • For unsupported file system types using logical images will ensure Nuix can still process the data  

Create a piece of Proof Finder evidence at the parent directory level. This ensures that all of the files are associated with the single image.
