# Editing an Alignment Override

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
Align left file (or folder) | with right file (or folder) | Description
x.txt | x.csv | Lines up "x.txt" with "x.csv".
*.gif | *.png | Lines up all GIF files with PNG files of the same name.
x*.jpg | y*.jpg | Lines up files such as "x1.jpg" with "y1.jpg" and "x2.jpg" with "y2.jpg".
