Don’t forget that email proliferates. The copy in your inbox could be just
one of many. Check your sent items, deleted items and draft folders. It’s
useful to empty out your sent items and deleted items on a regular basis in any
case as these count towards your total email quota.
Documents on your computer
When you delete a document on your computer it hasn’t really gone anywhere at
all. Normally it has just been relocated to the recycle bin. You should empty
the recycle bin on a regular basis. Technically it is still possible to retrieve
the document, but for most normal purposes we can assume that if it’s removed
from the recycle bin it has gone. When your PC is decommissioned or passed on ITS
will always ensure that data left on the hard drive is overwritten to make it
hard for anyone else to access it.
Documents on removable media
For a CD, memory key (USB drive) it’s just as easy to physically break it to
prevent future access. If in doubt, contact the IT Helpdesk
