Which of the following methods can help reveal information about deleted files?

The method that can help reveal information about deleted files is metadata examination. Metadata refers to data that provides information about other data. When a file is created, modified, or deleted, various metadata attributes are generated, such as timestamps (creation, modification, last access times), file size, and the location of the file on storage media. This metadata remains on the filesystem even after the file has been deleted, at least until that space is overwritten by new data.

By examining the metadata of a filesystem, forensic investigators can gather valuable information about deleted files, such as when they were created, when they were last accessed, and any previous modifications made to them. This can provide critical context in an investigation, helping to establish timelines or linking users to specific actions.

Other choices, while related to data and files, do not specifically aid in revealing information about deleted files in the same direct manner as metadata examination.
