uppercase=truefalse

If true, return the file extension in uppercase. As file extensions may be in mixed case, this option may simplify code handling file extensions.

The Extension and Basename commands return the extension and base name, respectively, of the file referenced by the filepath, path.

Extension("name.ext") returns "ext" and Basename("name.ext") returns "name".  Both commands omit any directories listed in path.

The filepath, path, must be syntactically correct but is not required to correspond to an existing file or directory.
