How to use the script

The script has no interface other than alert on launch to warn that files on disk will be altered, and alert when complete.

All links in the active InDesign document are renamed to eliminate spaces and punctuation that would require URL encoding. This prevents URLs that look like ".../This%20is%20the%20File%20Name.jpg". Instead such a link becomes ".../this-is-the-file-name.jpg".

The script is open source so it may be altered to suit other needs. For example, if lowercase is not desired, remove the change to lowercase. Other file name transformations can be added or removed, including to replace specific characters for a unique situation.

For help installing scripts, see How to Install and Use Scripts in Adobe Creative Cloud Applications.

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.
