Data erasure (sometimes referred to as data clearing, data wiping, or data destruction) is a software-based method of data sanitization that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by overwriting data onto all sectors of the device in an irreversible process. By overwriting the data on ...
The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files.Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...

The file manager, by default, displays hidden files because it does not follow Windows Explorer's policies. The tabs show name, modification ...
File deletion is the removal of a file from a computer's file system. All operating systems include commands for deleting files ( rm on Unix and Linux , [ 1 ] era in CP/M and DR-DOS , del / erase in MS-DOS / PC DOS , DR-DOS, Microsoft Windows etc.).
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
Running on a compatible operating system, it does not need a suitable extractor in the target computer to extract the data. [citation needed] The executable part of the file is known as a decompressor stub. Self-extracting files are used to share compressed files with a party that may not have the software needed to decompress a regular archive.
Windows File Recovery is a command-line software utility from Microsoft to recover deleted files. [1] [2] It is freely available for Windows 10 version 2004 (May 2020 Update) and later from the Microsoft Store. [3] Windows File Recovery can recover files from a local hard disk drive (HDD), USB flash drive, or memory card such as an SD card.
