> FileUtils.listFilesAndDirs behaves unexpected
> ---------------------------------------------

> URL: https://issues.apache.org/jira/browse/IO-495

> Affects Versions: 2.4

> The behaviour of listFilesAndDirs is quite unexpected in my opinion.
> FileUtils.listFiles searches for files in a directory, where the files match
> the filter, including the subdirectories which are matched by the dirFilter.
> FileUtils.listFilesAndDirs searches for files and directories, where the
> files match the filter and the directories match the directory filter,
> including the subdirectories which are matched by the dirFilter.
> But, if one extends the listFiles-method, the logical behaviour would be:
> FileUtils.listFiles searches for files and directories in a directory, where
> the files and directories match the filter, including the subdirectories
> which are matched by the dirFilter.
> This method has been discussed in
> https://issues.apache.org/jira/browse/IO-328, but there the point was, that
> listFilesAndDirs also includes the root folder, which was documented
> correctly after this bug. In my opinion, the problem not the inclusion of the
> root filter but the different behaviour from the listFiles-method.
> I'll provide an patch, where the method filters everything with the first
> filter and includes subdirectories if they are included by the dirFilter. One
> could also keep the current method, but imho it then should be named
> different as it behaves different than listFiles (maybe filterFilesAndDirs?).
