Safe Deleter Description

The application helps you to erase important data and in this way protect risky data from recovering after being deleted - it is assigned to erase all confident and important data permanently using intelligent wipe techniques. Bring your safety to next level - Safe Deleter implements the Department of Defense clearing and sanitizing standard DOD 5220.22-M, to give you confidence that once shredded, your file data is gone forever. One of the features of Windows compliance is that it implements object reuse protection. This implies that when an application allocates file space or virtual memory it is unable to view data that was previously stored in the resources Windows NT/2K/XP/Vista/7 allocated for it. However, when the operating system is not active it is possible to use raw disk editors and recovery tools to view and recover data that the operating system has deallocated. Even when you encrypt files with Windows' Encrypting File System (EFS), original unencrypted file data is left on the disk after a new encrypted version of the file is created. From the above-mentioned it follows that the only existing way to ensure that data erasure, as well as files that you encrypt with EFS, are protected from recovery is to use a secure delete application. Safe Deleter applications rewrite deleted file on-disk data using techiques that are shown to make disk data unrecoverable, even using recovery technology that can read patterns in magnetic media that reveal weakly deleted files. Safe Deleter is exactly a secure erase application. You can use Safe Deleter both to securely delete existing finance documents, as well as to securely erase any data that exists in the unallocated portions of a disk (including files that you have already deleted or encrypted). Safe Deleter can shred finance documents and data, to give you confidence that once deleted with Safe Deleter, your file data is gone forever. How Safe Deleter Works: Securely shred files that has no special attributes is relatively straight-forward process: the secure deleter simply rewrites data with one of the secure delete patterns. Windows NT/2K/XP/7 compressed, sparse and encrypted files-these are trickier. Such types of files are managed by NTFS in 16-cluster blocks. Тo handle them Safe Deleter relies on the defragmentation API. Using the defragmentation API, Safe Delete can determine precisely which clusters on a disk are occupied by data belonging to compressed, sparse and encrypted files. Once Safe Delete knows which clusters contain the file's data, it can open the disk for raw access and overwrite those clusters. Cleaning free space poses another challenge. Since FAT and NTFS provide no means for an application to directly address free space, Safe Deleter has to indirectly rewrite free space. First, Safe Deleter allocates the largest file it can. For this files Safe Deleter performs a secure rewrite, ensuring that all the disk space that was previously free becomes securely cleansed. On NTFS drives Safe Deleter's job isn't necessarily through NTFS allocates and overwrites the file. Safe Delete must also fill any existing free portions of the NTFS Master File Table with files that fit within an MFT record. All Safe Deleter has to do to take care of the free MFT space is allocate the largest file it is able to - when the file occupies all the available space in an MFT Record NTFS will prevent the file from getting larger, since there are no free clusters left on the disk. Safe Deleter then repeats the process. When Safe Deleter can no longer even create a new file, it knows that all the previously free records in the MFT have been completely filled with securely overwritten files. To rewrite file names, Safe Delete renames the file 26 times, each time replacing each character of the file name with a successive alphabetic character. For instance, the first rename of "foo.txt" would be to "AAA.AAA".
