AOL was the first ISP that I had and I signed up then for their email service - been all ok since, but I can't find if they have a process to transfer the present contents of my account to another PC or OS - I think when I changed my PC last I just started afresh. My idea is to have a copy of various items - Picasa photos, documents, etc, in case things go wrong!
My concern with file size was prompted by my transferring some photos to a CD (trial run) and running out of space, and I thought it would be useful to know how much I needed. Anyway, I'll copy what I can and sort things out after the upgrade.
Thanks for interest and reply.
