Backup directory
Used only when Backup=true and ResultDir is empty.
- Non-empty: write a timestamped <name>.<YYYYMMDD-hhmmss>.bak under this folder before overwriting the source.
- Empty (default): write <source>.BCK<N> next to the source, where N is the lowest unused integer (1, 2, 3, ...). CLI equivalent: --b <folder> (with arg) or --b (no arg, sibling).

- Result directory - Directory for formatted output. Empty = format in place.
- Output encoding - ANSI keeps each file's own encoding (BOM or detected UTF-8 preserved); UTF-8/UTF-16 convert the output (with BOM).
