What does the "Assigned value is never used" warning mean?

unformatted = unformatted.replaceAll(seperator, "\n");

Netbeans gives me the warning:

The assigned variable is never used

What does this mean?

The assigned variable is never used

The line itself self explaining.

Its becauseunformatted is initialized, but is never used, making the initialization unnecessary.

It helps you out to make your code cleaner and to get rid doff from unnecessary memory waste.

It means that you're not doing anything with that variable after you assigned a value to it. For example, you are not returning it, performing a calculation with it, passing it to a method, or anything else. It basically means that the variable has not been used after a value has been assigned to it.
