I'm always worried when making .tars that I'm doing something wrong when the file also has a . file inside. I know this is probably nothing but it makes me think of something like this.
. and .. are how terminals navigate around file systems.
The command
cd .
means "change directory (cd) to here (.)"cd ..
means "change directory to here, but one level up: my parent directory."So following that model, winrar and maybe older versions of 7zip used folders called '.' as navigational tools within the archive browser. If you double-clicked through them, you'd see where they go.
I don't know how much of this you knew, but the point is it shouldn't freak you out too see them.
