PDF Export Folder
Script for Adobe InDesign
The purpose of the script is twofold:
1. Export a folder of InDesign documents to PDF as simply as possible. Other scripts perform the same and more, and with more options. Users are encouraged to use those scripts when further capability is needed. The point of this script was to accomplish one specific task without excess.
2. Act as a template to create other scripts that process InDesign documents, whatever the process might be. The script can perform other tasks by altering the processFile() function, called for each InDesign document found in the selected folder. Also further options are easily added to the interface.
- Option to include subfolders
- Export using any defined PDF Preset
- Option to add suffix to output file names
- Option to replace existing output files.
- Adapt open source to customize or create other scripts
PDF Export Folder
How to use the script
The interface has two sections: Process and Options. Set desired options then click the OK button to begin. A progress bar is displayed as documents are processed.
Section 1: Process
Folder — select a folder that contains InDesign documents. Each will be exported to a PDF in the same folder. Only files with the .indd extension are processed.
Include subfolders — if enabled, documents in all subfolders are also processed.
Section 2: Options
PDF preset — the PDF preset used to export the InDesign files.
Original file name + — a suffix of characters appended to each output file name. The characters entered must be legal to use in file names. Any illegal characters are automatically removed. Having no suffix is allowed, in which case output file names exactly match input file names.
Replace existing output files — when enabled, existing output files are replaced. When disabled, the user is asked to confirm the replacement.

IMPORTANT: scripts are developed for the latest Adobe Creative Cloud applications. Many scripts work in CC 2018 and later, even some as far back as CS6, but may not perform as expected, or run at all, when used in versions prior to 2018. Photoshop features Select Subject and Preserve Details 2.0 definitely fail prior to CC 2018 (version 19) as the features do not exist in earlier versions. For best results use the latest versions of Adobe Creative Cloud applications.
