If you are concerned that someone may gain access to the data files,
yes then you can delete them so they will not be easy to recover with
special software.
In which case you should run a special disk wipe software package
(see below) after you format the drive.

Note: Use the DOD method (at least 7 passes) for 'Unused/Free' space,
Make absolutely certain that you have selected the correct Windows drive
letter!!!
If the PC has a Restore Partition you don't want to wipe it clean.
Next thing is to do a 'Clean Install' of Windows XP.
This assumes that you have all the media (CDs) that came with the PC.
Note that some manufactures may not provide a Windows XP install CD but have
a hidden recovery partition, in which case you need to read the
documentation.
If you have a Laptop: The Windows Key Code sticker should be on the bottom
of the laptop
(you will need this to do the install).
If you have a Desktop the Key Code sticker may be on the side of the case or
with the CD Media
Note: make certain you have a 'Drivers' CD, if not go to the manufacturer's
web site and download all the drivers (Video, Sound, Network, Etc.).
If your PC came with a Windows XP CD then you can perform a clean install
per
the info provided at the last part of this post.
Before you do the 'Clean Install' download and install the following
utility:
Belarc Advisor:

It does a good job of providing a wealth of information, including installed
software and hardware configuration.
Now if you choose to do that clean install of Windows XP, here's how!!!
How to do a Clean Install of Windows XP:
Note: If You have a Windows XP CD: Change the BIOS setting to Boot from CD
drive first.
Then see below:

Again note: Make sure you have the drivers you need for your motherboard,
video card, sound card, Etc.
If you are doing a Clean Install on an existing PC that has XP already
installed:
Verify your CD or Sticker Key code matches what Belarc Advisor reports for
your existing install.
Note: OEM Windows (installed at the factory) installations usually have a
sticker
located on the PC or laptop case and may not match the factory installed key
as reported by Belarc Advisor.
This is normal as the factory uses their own internal key code,
you need to use the code on the sticker.
