The hard drive has 160gb so I may well clean it and load it with an old W98 disc I have. This will not take up a lot of room so I can transfer about 60 years of photos and films taking care to copy sections to discs.
I have the kit to transfer and all of it is old enough to work with W98.
I'm not worried about security; it will be a storage only so will not be connected to the internet by Ethernet or wireless..
The purist may well suggest an external hard drive but being connected to a computer it could pick up another virus.
