4Neurons Eraser

4Neurons Eraser is a reliable application that was designed to help you delete files so that their recovery becomes impossible.
Standard "Delete" method provided to you by the operating system, doesnt really destroy the data on your hard drive, it merely removes the filename from the directory list, and marks space occupied by your file as free. Entire content of the file (thus file itself) is still there and can be easily recovered!
4Neurons Eraser physically erases the content of the file, overwriting it multiple times with random data, just before deleting. 4Neurons Eraser uses custom pseudo-random number generator with enormous period and large seed value.
Overwriting the files multiple times with random, chaotic data, which cannot be reconstructed, is critical, since some of the companies that specialize in data recovery or government agencies are capable of recovering the files that have been simply erased (ie: overwritten once with constant value), using dedicated hardware.
4Neurons Eraser comes as Windows shell extension and as a console program. Shell extension integrates itself with Windows Explorer allowing you to erase your files as easily as deleting them is.
In the Windows Explorer select files/directories you want to erase, then click with right mouse button and choose "Erase" menu item, which is just below Delete (see screenshot to the right). 4NErase.exe is program for console usage and allows you to erase a single file or recursively entire directory. It also supports wildcards for erasing multiple files/directories at once.Limitations in the unregistered version30 days trial
