# Rename a batch of files predictably

A small illustrative toolbox for repeatable developer tasks\.

Read the proposed mapping before applying it, so the result is never a surprise\.

## Preview before applying

A predictable batch rename is a two\-step habit: produce the proposed old\-to\-new mapping first, read it, and only then apply it\. The preview is what turns an irreversible bulk edit into a reviewable one\.

## What this page exercises

This use case is illustrative\. It shows the shape and route of a use\-case page rather than describing a released capability\.
