In Java, How can I programmatically identify a hidden file in a zip?

I would like to ignore hidden files when extracting a zip. Is there any way i can identify that a ZipEntry belongs to a 'hidden' file?

Java class ZipEntry does not maintain file flags by design, as the accepted answer found.

If your usecase has not reserved the comment tag, you could fill it with file flag info, as e.g. windows command line attrib <file> delivers. In order to mark only hidden files, that would be

ZipEntry entry = new ZipEntry("foo").setComment("H");

EDIT

There is also an extra tag, designed to take additional implementation specific information as generic container, see this answer

If this is on Windows, there is no way to do it. The ZipEntry doesn't contain such information. You might be able to write your own zipper to store the information in ExtraInfo field.

On Unix, you can workaround by checking the leading dot in the filename.

It should have been preserved when they created the zip.
