recursive(+Boolean)

If true (default false), recurse into subdirectories

follow_links(+Boolean)

If true (default), follow symbolic links.

file_type(+Type)

See absolute_file_name/3.

extensions(+List)

Only return entries whose extension appears in List.

file_errors(+Errors)

How to handle errors. One of fail, warning or error. Default is warning. Errors notably happen if a directory is unreadable or a link points nowhere.

access(+Access)

Only return entries with Access

matches(+GlobPattern)

Only return files that match GlobPattern.

exclude(+GlobPattern)

Exclude files matching GlobPattern.

exclude_directory(+GlobPattern)

Do not recurse into directories matching GlobPattern.

hidden(+Boolean)

If true (default), also return hidden files.

This predicate is safe against cycles introduced by symbolic links to directories.

The idea for a non-deterministic file search predicate comes from Nicos Angelopoulos.
