Jamie is using the UNIX file system to work on his computer. He puts a dot before the file extension to separate it from the filename. How does the UNIX file system interpret the dot?

As a seperator before a file extension

As a character in a file name

As the name of the current folder

Or as the name of the parent folder

Explanation:

The dot is simply another character in the file name. It is only specific applications that detect the dot as preceding a file extension.
