The easiest way to get files to LPI for your project is to login and upload files directly from your account. Or you can FTP directly using windows or any FTP client, with the following location as well:
Site: ftp.lpiprint.net
User: lpiftpuser
Password: LPIfiles1
(this password is case-sensative)
If using direct FTP, please make sure that you contact LPI to make sure your files are properly attached to your project.
If you need an FTP client, please visit the FileZilla site, which offers options for PC, Mac, and Linux!
