ArrayList is probably a better choice than the hoary Vector class for a java.util.List implementation. You can always add synchronization to it using java.util.Collections.synchronized...() methods. Set might also be a suitable interface, since you likely will not need to list the same file twice in the collection.

Hash table?

java.util.HashMap is probably the better choice for a hash table (i.e., java.util.Map) implementation compared to java.util.Hashtable, with the same considerations as ArrayList vs. Vector.
