When you delete a file from your hard drive, the information remains even though we cannot access it, so it is possible to recover the data using certain programs. This is very useful if you delete files by mistake, but it is inconvenient if we want to make sure that no one can recover what we deleted.
Blank and Secure is a lightweight and portable application that completely deletes files without the possibility of recovery, so it must be used with care and only when we are sure that we want to get rid of the file forever.
Its operation is simple: before deleting each file it replaces it with zeros, so that is the only thing you get if you use some kind of recovery tool. So if you want to completely hide the trace of what you delete, with this application you can erase with total security.
