📂 Analyze one or multiple PST files at the same time

Sometimes an inbox can become so large that a single PST file is no longer enough. It will then be split into multiple PST files, complicating its processing. With Pesto, whether you have one file or many, it’s all the same! Load them all and start your processing without delay.
