What is a "logical image" in the context of FTK?

A logical image refers specifically to an image that captures only specific files and folders from a storage device, rather than duplicating the entire disk. This type of imaging is often used in forensic investigations when only certain data is needed, allowing examiners to focus on relevant files while minimizing unnecessary data handling and analysis.

Logical imaging can be particularly useful when dealing with large volumes of data. For instance, if an investigator is only interested in documents or specific types of files, creating a logical image allows them to expedite the process while preserving the integrity of the data they intend to examine.

In contrast, an image that captures the entire disk encompasses all data, including deleted files and system files, which can lead to larger and more complex data sets that are not always necessary for a particular investigation. Cloud storage images and those that do not preserve metadata are distinct concepts that do not fit the definition of a logical image, as they pertain to different aspects of data management and forensics.
