I have always kept old emails in the LOCAL folders for security reasons not having all my info on a server somewhere that could be comprimized/stolen/scammed. I am now on Yahoo and have heard security is not the best so I am not sure I want to put all these files on their servers. Now, however, as my PC is getting old I am afraid it could crash, I assume I would loose all those emails-correct?. If I go into my TB Profile and find the Mail/Local Folder I can copy and paste it to a flash drive. Would that be the recommended way to back up? If I did this process a month from now would it, like a file, ask me to overwrite what is already there and add anything new? If my PC did crash, could I do the reverse and copy and paste that flash drive Local folder into my new TB profile? Thank You.
