Merge All Files in Each Subfolder into a Single PDF File

AutoSplit plug-in for Adobe® Acrobat®

Introduction
In this tutorial, we will demonstrate how to merge all files in one or more folders into single PDF files. Doing this manually for the contents of one folder at a time would be a slow process. AutoSplit™ features a tool that quickly executes this procedure on the contents of multiple folders at once.
Merged files can be saved within corresponding folders or placed in a specified output location. All file formats supported by Adobe Acrobat can be converted into PDF and merged into output files. One output PDF file is created for each input folder – and named after it. Each of the merged input documents are also bookmarked within the output PDF.
In the steps below, the goal is to merge the contents of x3 input folders into individual PDF files. Each output file is saved to the corresponding input folder, and named after it:
