Format Specifiers

Every keyword you can use to build custom output file names and folder structures.

Here is the full list of supported format specifiers and the data each one corresponds to. Enclose any specifier in curly braces (e.g. {trackTitle}) when using it in a custom naming scheme.

Tip: If a tag is missing, everything inside the brackets of that specifier is skipped. Put separators (dashes, spaces, "of", etc.) inside the braces so they vanish along with the missing tag. See Output Directory & File Naming for worked examples.
