Secure Delete is a Java security tool designed to help you to maintain your privacy and the privacy of your data. When you delete a file on your computer, your computer erases where the file was stored and allows the space it was using to become free space and be used by other files. Until you have used this exact bit of the free space available these files will be recoverable by anyone whom wishes to. Secure Delete works by deleting files is a special way - the files are overwritten before they are deleted, meaning that even if the deleted file pointer is recovered no one can salvage any of the original data that was in the file. Secure Delete can also clear all of the free space on your hard drives - this will ensure that any other data on your drive ( files that were deleted normally, files used by applications etc. ) has also been erased and is unrecoverable.
