The Settings tab allows you to set global options in pdfFactory.  

The AutoSave feature saves entire contents of pdfFactory sessions automatically. This is useful in case you need to get back to something you printed previously or if you suffer a system crash while printing.

You can set the number of complete sessions to save using the spin control provided. The PDF files are saved in My Documents\pdfFactory files\AutoSave files by default. Default file locations for manual and auto-saved files can be set using the "Folder locations" button. The AutoSave files can be deleted using the "Delete auto-saved files" button.
