A sequence lets you save a set of stored operations for one or more PDF files. The sequence will process the files automatically using the commands and parameters that are defined in the sequence. This is in effect a predefined workflow.
This is how to copy Power PDF Sequences from the computer where they were created to a new computer.
Sequences are stored in "%APPDATA%\Nuance\PDF\NuancePDF\Sequences". Copy them from this folder on the computer with the defined sequences into the same folder on the new computer and they will be available in Power PDF on that computer.
