# Reduces texture sizes in a folder by converting DDS/TGA files to JPG/PNG using ezTexConv,
# and optionally optimizes the resulting JPG and PNG files.
#
# Usage:
#   ./reduce-texture-sizes.ps1 "C:\path\to\folder" [-Convert] [-OptimizeJpeg] [-OptimizePng]
#
# Options:
#   -TargetFolder   Folder to process recursively. Defaults to current directory.
#   -Convert        Run ezTexConv in reduce mode to convert DDS/TGA to JPG/PNG (deletes source files).
#   -OptimizeJpeg   Run optimize-jpeg.ps1 on all JPG/JPEG files afterwards.
#   -OptimizePng    Run optimize-png.ps1 on all PNG files afterwards.
