Can deleted files be recovered?
Each situation is unique, but it is often possible to recover deleted files with a computer forensic investigation. Most operating systems do not erase the actual data; they erase a pointer to the file so that the file does not appear in the folders or directories. These files can be recovered by a process of undeleting the file by restoring the directory entry. In other cases, if the directory entry is not available then a file can be recovered by using a powerful process called file carving to obtain fragments of files when directory entries are corrupt or missing.
