Thanks for your speedy replies. Sorry I wasn't here - been cooking!
Kite/Kate - thanks for this. I didn't think of corruption problems, and thanks for the explanation about FTM on someone else's computer. I'm visiting a rellie in a few weeks time to compare FH research notes, and I thought it would make it easier if I took my memory stick - I see it won't be as simple as that! I'll check if she has the programme on her 'puter.
Ah, Wendy - another handy tip! I'll do that.
Glen, if I understand you correctly, I'll need to work on my computer, and save onto my memory stick each time I've changed something so that I have up-to-date versions on each place - computer for working on and memory stick for backup.
I expect someone will put me right if I've misunderstood your instructions.
(My daughter was very impressed, as I loaded the memory stick and saved my photos, certs and FTM onto it
all by myself!

I used the 'r-click: properties: copy: then drag copy onto removable drive E' method - hope that's right, seems to have worked!)
Bee.
