# Editing an Alignment Override | Top

Fill in the Align left file (or folder) and with right file (or folder) edits. Mark the Regular expression checkbox to interpret them as replacement-style regular expressions. If you used DOS wildcards like * and ?, leave it unmarked. Fill in the Limit to this folder edit to specify a relative path for the alignment. Examples
