Slack Space Definition: Slack space is the unused area in a disk cluster after a file's data, often holding deleted-file remnants valuable in digital forensics.
Slack space is the unused area between the end of a file's actual data and the end of the disk cluster or block allocated to it. Because operating systems do not always overwrite this leftover region, it can retain fragments of previously deleted files, making it a valuable source of evidence in digital forensics. Investigators examine slack space to recover hidden data, while attackers may abuse it to conceal information.
