Why is it crucial to recover deleted files in investigations?

Recovering deleted files is crucial in investigations primarily because they often contain important evidence that can be pivotal in establishing facts, timelines, and user actions. In many cases, deleted files may hold key data such as emails, documents, or images that provide insights into activities or intentions relevant to the investigation. This evidence can be critical in legal contexts, where proving a connection to the crime or a specific action taken by individuals may hinge on this recovered information.

The value of such evidence can extend to corroborating witness testimonies, establishing alibis, or even revealing motivations and communications that were thought to be lost. This is why forensics tools and methods focus heavily on the ability to recover and analyze these deleted files, as they can often lead to significant breakthroughs in an investigation.
