For details on how to use the scripts and macOS Automator quick action see the following blog post:
Script purpose and workflow:
Run SnapshotImageFinder.py to identify iOS snapshot images and extract them from a targeted iOS file system extraction directory. These files end with @3.ktx or @2.ktx.
Extract the macOS Automator quick action from the ktx_quick.zip file. With it convert all the .ktx files extracted in step #1 to .png format.
Run SnapshotTriage.py to extract, parse and match the images with the snapshot metadata contained in the extracted bplists from the applicationState.db datastore. This script accepts 2 parameters, the directory where the applicationState.db is located and the directory where the .png files are located.
After execution of the previews steps a triage report directory will be created containing the extracted bplists and iOS snapshot reports in HTML per app.
