Most of us have some data-files that we probably would not want to share with others, such as passwords, personal information, classified documents from our work, financial information, and more. Many of this information has already been stored on your computer, but when it comes time to remove it from your hard drive, things are starting to get a bit trickier since permanently deleting them is not as simple as you think.
The first thought is probably that we are simply deleting the file and the data is lost. Unfortunately this is not enough, since when you delete a file, the operating system does not actually remove the file from the disk but only removes the file reference from the file system table.
The file stays on the disk until another file fills it up, but even after that, it can be easy to recover your data using appropriate programs. Eraser is an advanced Windows security tool that lets you erase completely sensitive data from your hard drive without the worry that someone else may recover it.
The way to use it is simple, after installing the application, right-click (or right-click) the file (s) you want to delete to select the Eraser icon and click delete.
OPERATING SYSTEM: Windows
