BOAC,
Thanks for that

.
I think the external drive is the route to go down to be honest. My mum and dad joined this IT game only quite recently and I want to make things as simple as possible for them.
If we opt for an external drive (200Gb for example), I can format it from FAT to NTFS, load on my dads video software (which is Sonic MYDVD or something that sounds like that), then he can save his files without any worry.
I'm not the most patient person to try and teach anything to anyone, and I've already 'snapped their (mum and dad's) heads' off over trying to explain that all 'Temp' video files must be removed because they are clogging up the 'C' and 'D' drives
Cheers PD
