There are lots of ways to hide files of varying levels of sophistication. Below is a far from exhaustive list but should give you some ideas.

Adding a '.' in front of the filename, as you suggested, hides it from casual view using ls.
The best place to hide a letter is on the mantlepiece. Hiding something in plain sight is often very effective. It's still popular to name a directory ... if you want to hide it since it's hidden and easily overlooked among . and .. or you can put the file in a location someone is not likely to look e.g. /usr/lib/
You can create trojaned system binaries (rootkit) to ignore certain filename.
A kernel level rootkit
Put the files on a partition not mounted by defafult and mount it when you want access
Removeable media
Encryption

The way you hide files depends on why you need to hide them and from whom you are hiding them.

Regards,
Jim

the only way to "totally hide" a directory is with a rootkit.

if you need to hide something in plain site i would stick it in /dev in one of the random dev folders with a .foldername

I conspicuously left steganography off the list. Now that's really hiding in plain sight.
