Do you mean saved programs or are you talking about documents pics etc.?
You can buy a 64gb flash drive for less than £20 or a 500 Gb USB hard drive for sub £40 the latter will certainly be enough you can just drag and drop onto the new drive no speacial software is needed
Just check any hardware you have like graphics cards sound cards etc which are installed onboard your laptop -. have a Windows 7 driver (check manufacturers site) - a clean install is always preferable
