You should work in the following way:
When you start work on a workstation, first click on the Explore my Computer icon and copy any files from a previous session (held on floppy disk or on your M:drive) onto the D: drive.
Start your
software application,
open your file on the D: drive from
within the application and then carry on with your work, saving regularly onto the D:
drive.
When you have finished your session, close down your application, return to Explorer and make copies of your work onto the M: drive and also onto at least one floppy disk.
By doing this you have a very good chance of ensuring you have taken the best steps to safeguard your work.
Computers rely on their hardware and environment to perform
amazing tasks, but they are not foolproof.
Things can and do go wrong and you must be aware of this.
