That's not completely true: ":" is an invalid character for Windows 
filenames.

	touch "Foo:Bar"

does not returns an error but does not create a file called "Foo:Bar", 
instead it creates a file called "Foo" and associate to it a NTFS stream 
(I think this is the correct name) to it.

If you try an ls you'll see that your directory contains a file called 
"Foo". But try, for example:

	echo Hello >> Foo
	echo Good morning >> "Foo:Bar"

	$ cat Foo
	Hello

	$ cat "Foo:Bar"
	Good morning

	$ rm Foo

	$ cat "Foo:Bar"
	cat: Foo:Bar: No such file or directory
