Eraser is a Windows utility that allows you to securely erase files, file slack space or cluster tips (the space that is not occupied by the data in a file, but nonetheless allocated to that file by the operating system), Windows virtual memory swap file, unused space on a hard disk, or an entire hard disk or floppy disk or Zip disk or the like. It is able to wipe data using pseudo-random data (or any combination of data that you specify), any number of times you wish (eg, once, or using the US Department of Defense (DOD) recommendations of either 3 times or 7 times, or the Gutmann recommendation of 35 times, etc). It is also able to erase the filenames in the directories for files you delete. The program is open source and works under Windows.
With File Shredder you can remove files from your hard drive without fear they could be recovered. There are quite a few software tools today for retrieval of deleted files under Windows OS. Those tools, often referred to as “file recovery” software, are taking advantage of shortcoming of WIndows “delete” command that we all use regularly to delete files. Actually, the “delete” operation in Windows only removes bits of information from files so they appear deleted in OS. It is easy to retrieve those files using aforementioned specialized file recovery software.
In order to remove, or shred files permanently from your system you have to use a program that is capable of rewriting the files with random series of binary data multiple times. This process is often called shredding. That way, the actual content of the file has been overwritten and the possibilities to recover such a shredded file are mostly theoretical.
