McAfee Privacy Service Why Windows leaves file remnants To permanently delete a file, you must repeatedly overwrite the existing file with new data. If Microsoft Windows securely deleted files, every file operation would be very slow. Shredding a document does not always prevent that document from being recovered because some programs make temporary hidden copies of open documents. If you only shred documents that you see in Explorer, you could still have temporary copies of those documents. We recommend that you periodically shred the free space on your disk drive to insure that these temporary copies are permanently deleted. NOTE With computer forensics tools, tax records, job resumes, or other documents that you had deleted, could be obtained.
