'Umbenennen' (to rename) is a separable verb. The prefix 'um-' goes at the end in a main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Ich benenne die Datei jetzt um.
I am renaming the file now.
The verb consists of the prefix 'um-', which here indicates a change, and the verb 'benennen' (to name). So the meaning is literally to 'name something anew'.

'nennen' and 'umbenennen' both have to do with names. You use 'nennen' when someone or something is given a name or is referred to that way. You use 'umbenennen' only when there is already a name and that name is changed. Learners may confuse the words because both connect an object with a name. The simple rule is: 'nennen' is about a name, while 'umbenennen' is about a new name replacing the old one.
