GenSpec: A File Fragment Classification Approach
2020 International Conference on Computing and Information Technology (ICCIT-1441), 2020Collection and analysis of data are at the heart of digital forensics. However, in real-life situations, the data of interest is often found in files that were partially erased or otherwise tampered with. Consequently, identification of the file types of those fragmented files and the data format of the text contained in each file are deemed necessary.

A Survey on File Defragmentation Techniques on Modern Storage Systems
Information and Communication Technology Convergence, 2023File fragmentation is one of the widely studied subjects for several decades due to its considerable degradation on I/O operations. Also, it is a well-known problem in academia that file fragmentation on HDD disks can extremely lower the throughput and ...

Neural Networks for File Fragment Classification
2019 42nd International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2019Abstract - File fragment classification is an important step in file forensics in which filetypes are assumed based on their available content fragments. Methods typically used for this task utilize machine learning techniques on features like byte frequency distributions and fragment entropy measures.

Resurrection: A Carver for Fragmented Files
2014The recovery of deleted files is an important task frequently carried out by professionals in digital forensics and data recovery. When carried out without information from the file system, this process is called file carving. The techniques implemented in today’s file carvers are mostly sufficient for non-fragmented files.

Dynamic storage fragmentation and file deterioration
IEEE Transactions on Software Engineering, 1986As a result of insertions and deletions, a file tends to be cluttered with deleted records which are physically present. These unwanted records cause fragmentation within the file and give rise to additional access overhead because they have to be skipped over during processing.
