Indexed I/O has the ability to process files that are password protected. However, the passwords must be added to the project prior to processing. To do so, go to the admin tab on the left side of your screen, then click on the passwords tab. Enter the password for the file in the field, then click "Add password". You can do this for multiple passwords. When the system encounters a password protected file during processing, it will attempt to open it using each password added to this page until it is successful.
