How safe is a list?

[matalog]

I am using a List that must be global, as I did not define it as local.

It contains information that I would prefer not to lose, history of work.

If, as seems to happen once every couple of months, I have to use the Reset button at the back of the calculator to reset it, will the List still be there when the calculator resets?

If the answer is no, then how might I back this up to somewhere safer on the calculator?

What could possibly lead to losing the list?

The function AFiles (and/or AVars) could be a solution.

2.idea: display the contents of your list, copy it, and store them in a Note.
