Finding File Fragments in the Cloud [PDF]
, 2012 As the use – and abuse – of cloud computing increases, it becomes necessary to conduct forensic analyses of cloud computing systems. This paper evaluates the feasibility of performing a digital forensic investigation on a cloud computing system. Specifically, experiments were conducted on the Nimbula on-site cloud operating system to determine if ...

DFS: a de-fragmented file system [PDF]
Proceedings. 10th IEEE International Symposium on Modeling, Analysis and Simulation of Computer and Telecommunications Systems, 2003 Small file accesses are still limited by disk head movement on modern disk drives with the high disk bandwidth. Small file performance can be improved by grouping and clustering, each of which places multiple files in a directory and places blocks of the same file on disks contiguously.

Predicting the types of file fragments
Digital Investigation, 2008 A problem that arises in computer forensics is to determine the type of a file fragment. An extension to the file name indicating the type is stored in the disk directory, but when a file is deleted, the entry for the file in the directory may be overwritten.
