The verb ajourføre (pronunciation below) means to “supply with new information to thereby ensure actuality and accordance with the latest development”, according to the dictionary. It's meaning is not exactly the same as “to update”, for which you can use a different Danish verb, at opdatere, as in jeg har opdateret indstillingerne på min computer (“I’ve updated the settings on my computer”). Easier if you speak French and know how to pronounce jour (day), ajourføre is approximately pronounced “a-joour-fur”, with the “j” given the French-style “zh” sound and “fur” pronounced similarly to how you would say “fur coat” (but don’t pronounce the “r”).
