<h1>Free Space Eraser (wipe)</h1>
<p>Deleted files are not physically removed from your hard disk. When you delete a file, your hard disk just marks the file as deleted, but the data of the file is still on the hard disk. This is made to optimize performance and there are many tools available which can let others easily recover your sensitive files even after you format your hard disk.</p>
<p>Because the files are not phisycally deleted, after a while your hard-drive's free space is not actually free - it is filled with scrappy data from deleted files. To protect this data you have to <b>erase</b> you HDD free space</p>
<p>System Purifier physically erases your free space, by overwriting it <strong>several times</strong> with zero data.</p>
<h2>Erasing files and folders</h2>
<p>Navigate to "Free Sapce Eraserr" tool. Choose a drive and click "Clean" to <strong>wipe free space</strong>.</p>
