file carving

A variable-length file fragment (VFF-16) dataset with 16 file types is to reflect the file system fragmentation. The sequential memory sectors contain contextual information about file fragments. The 16 file types are ‘jpg’, ‘gif’, ‘doc’, ‘xls’, ‘ppt’,  ‘html’, ‘text’, ‘pdf’, ‘rtf’, ‘png’, ‘log’, ‘csv’, ‘gz’, ‘swf’, ‘eps’,  and ‘ps’. We split the dataset into the training and test sets with a ratio of about 4:1.
