Override vs. Overwrite

“Override” and “overwrite” can both involve replacing an existing result, but they describe different actions. “Override” commonly means setting aside or superseding a rule, decision, setting, or control; “overwrite” commonly means replacing existing stored information with new information.

Quick answer

Use “override” when one rule, choice, setting, or control takes precedence over another. Use “overwrite” when existing data or text is replaced by new material.

Further guidance

Boundary

The words can occur in the same technical workflow, but they are not interchangeable: changing which rule wins is different from replacing the underlying stored content.

Override Use

Use “override” when a higher-priority instruction, manual action, setting, or decision cancels or takes precedence over the normal one.

Overwrite Use

Use “overwrite” when new information is written in place of information that was already stored, especially in a computer file or storage context.
