To copy files the easiest way is to display the files inside a window, such as "My Documents" or "Windows Explorer"
Here is how My Documents may look:

In the FIRST window what you then need to do is display the files from your OLD computer.
You then need a SECOND window showing the files on your diskette or on your USB drive (which may be empty).
So you have TWO windows displayed, one showing the SOURCE the other the TARGET.
In the FIRST (source) window select the file you want to copy, hold down the RIGHT mouse button, and DRAG it over to the second (target) window.
Let go of the mouse button then select COPY from the little menu.
The file should then be copied from the SOURCE to the TARGET.
Continue to do this till all the files have been copied (if you are using a diskette you may not be able to get many files on there).
Now go over to the NEW PC and do the reverse, copy the files from the diskette or USB drive, to the new hard disk.
Try to use the same folder names.
Having re-read my own text I realise it is almost impossible to explain to someone how to copy files from one place to another.
It may be easiest to find a friend or neighbour who knows a lot about computers and ask them for help. It may take them minutes whereas you may get into a right mess and even finish up deleting files by accident.
