Extension Command Test Data

This directory contains sample files for manual and automated validation of the renamer extension workflow. To avoid mutating source fixtures directly, copy the sample/ folder to a temporary location before running commands that perform real filesystem changes.

Example usage:

TMP_DIR=$(mktemp -d)
cp -R testdata/extension/sample/* "$TMP_DIR/"
go run ./main.go extension .jpeg .JPG .jpg --path "$TMP_DIR" --dry-run

The sample set includes:

• Mixed-case .jpeg/.JPG extensions
• Nested directories (sample/nested)
• An already-normalized .jpg file
• A hidden file to verify --hidden opt-in behavior
