For VOCALOID4 Voice Banks, the installation DVD might contain breath files in its WAV folder.
Use a drag-and-drop operation to paste a breath file on a WAV (MONO) track, or under the "File" menu, select "Import", and then "Wave (W)".
Note that some Voice Banks might not contain breath files. If you have any questions, contact the distributor of your Voice Bank.
