The RAR (Roshal Archive) file format is widely used for data compression and transportation. In digital forensics, recovering partially corrupted or fragmented RAR files is crucial for evidence preservation. This paper presents an automated file carving method based on content and structure analysis, designed to handle fragmented RAR archives. We apply mapping functions to identify headers and footers, followed by an enumeration technique to reassemble fragmented segments. 1. Introduction
The distance between the detected header and footer is used to determine if the file is continuous or fragmented. Sedados rar
Mapping functions are applied to scan raw data to locate the unique signatures of the RAR header and footer. The RAR (Roshal Archive) file format is widely
A checksum verification is performed to ensure the repaired file is usable. 3. Experimental Analysis We apply mapping functions to identify headers and
The automatic carving of RAR files is essential for forensic investigation. The presented approach provides a reliable tool for reconstructing fragmented or partially overwritten RAR archives, directly contributing to the integrity of digital evidence.
RAR is a popular proprietary lossless compression archive format (WinRAR).
