What does the term "carving" refer to in the context of digital forensics?

In the context of digital forensics, "carving" specifically refers to the process of extracting files from unallocated or deleted space on a storage device, such as a hard drive. This aspect is crucial as it allows investigators to recover files that may not have a corresponding directory entry, meaning they aren't easily accessible through the standard file system navigation. Carving relies on identifying file signatures and patterns that indicate the presence of files, enabling the recovery of data that may have been intentionally or unintentionally deleted.

This technique is particularly important for forensic analysis, as it helps uncover evidence that could be relevant to an investigation, such as deleted documents, images, or other types of files that may have been removed by a user but still exist in fragments on the disk. The ability to recover this data can be critical in legal contexts, where proving the existence of certain files or data can influence the outcome of a case.
