Message: [QUOTE="Zig, post: 3483529"] You are right, FileOutputStream & FileReader are pretty primitive. ObjectOutputStream, OTOH is a different matter. ObjectOutputStream will keep references to objects written to the stream, which enables it to handle cyclic object graphs, and repeating references of the same object are handled predictably. You can force ObjectOutputStream to clean up by using: treeOut.writeObject(binTree); treeOut.reset(); This should notify ObjectOutputStream that you will not be re-referencing any previously written objects, and allow the stream to release it's internal references.
