Abstract
Deleted file recovery tools use residual metadata left behind after files are deleted to reconstruct deleted files. File systems use metadata to keep track of the location of user files, time stamps of file activity, file ownership and file access permissions. When a file is deleted, many file systems do not actually remove the file content, but mark the file blocks as available for reuse by future file allocations. This paper describes a strategy for testing forensic tools that recover deleted files from the residual metadata that can be found after a file has been deleted.
