FileUtils.listFiles() doesn't return directories
------------------------------------------------
Key: IO-173
URL: https://issues.apache.org/jira/browse/IO-173
Project: Commons IO
Issue Type: Improvement
Components: Utilities
Affects Versions: 1.4
Reporter: François Loison
FileUtils.listFiles() returns only files and not directories.
So it can't be used to retrieve sub-directories.
Some fix could be applied:
private static void innerListFiles(Collection files, File directory,
IOFileFilter filter) {
File[] found = directory.listFiles((FileFilter) filter);
if (found != null) {
for (int i = 0; i < found.length; i++) {
if (found[i].isDirectory()) {
>>> fix
if ( addDirectories ) {
files.add(found[i]);
}
>>> end fix
innerListFiles(files, found[i], filter);
} else {
files.add(found[i]);
}
}
}
}
