Carving tools are essential in digital forensics for Data Recovery of deleted or hidden files from disk images, unallocated space, or memory dumps. File carving refers to extracting files from raw data, even when the file system is corrupted or no longer exists. These tools work by identifying file headers, footers, and other signatures, allowing investigators to reconstruct deleted or fragmented files and extract relevant information for their analysis. Carving is widely used in cyber investigations to recover lost evidence, analyze malware, and uncover crucial data.
