zapatafa is on a distinguished road

I wanted to test some potential destructive code on a directory and all its subdirectories. So, I tarballed it and then made a copy from the tarball in a space where my code wouldn't accidentally obliterate anything that I really wanted to keep. My code seemed to work except that I noticed that certain files were not put into the tarball.

This is what I originally did:

Code:
 tar -czf mydirectory.tar.gz directory
In the safe location I then did the following:

Code:
 tar -xzf mydirectory.tar.gz
I ran a recursive diff on the archived and original directories. This showed that certain files where missing.

It seems that any file named .__<name>__ were not recorded in the archive. For example,

Code:
.__quiz__
or

Code:
.__example__.
What is tar skipping over these files? How do I get tar to include them? What other files might tar not record?

Even if I ran tar in verbose mode, there was no message that things were being skipped over.

UPDATE

I installed "gnu's" version of "tar" and that works as expected. Everything is correctly archived.

So, why doesn't the natively installed "tar" do the right thing?
