Eraser is a program that allows to delete files from a hard disk, or other storage devices, permanently, being inaccessible even by specialized applications in data recovery, as is the case of Recuva, for example.
There is personal information such as: passwords, bank account data, compromising photos, or other files, which at some point may need to have to be deleted to leave no trace. A sure and foolproof method to achieve this is through this application.
Deleting the files does not mean that someone can not recover them, despite having deleted them from the hard disk using the usual Windows procedure. This is because the operating system removes the reference to the memory space where the data that makes up the file is located, but it does not delete the data itself. The space is free to be busy again, but while this is not done, it will be possible to recover the deleted files .
It has several erasing algorithms, such as DoD, Pseudorandom Data, or Gutman (with up to 35 overwrite passes); And you have the possibility to configure the deletion by selecting a combination of these methods.
Eraser integrates to the context menu of the Windows explorer, therefore you can delete any file or folder directly without having to open the program. In case it is not important that a particular file can be recoverable it is not recommended to use this method since it takes longer than normal erasure. Deleting an entire hard drive can take several hours.
Eraser 6.0.10 is the latest version, updated in November 2012, of this software that can be downloaded for free. Works on Windows XP, Vista, 7 and 8.
