Help FAQs states:
Past versions of LimeWire used the following folders to save and share files:

C:\Documents and Settings\Your username\LimeWire
or
C:\Documents and Settings\Your username\My Documents\LimeWire

The concept of a shared folder is not longer present to avoid inadvertent sharing. Instead, you can add folders for LimeWire to manage and through My Library set which files to share or unshare using the Share Widget.

I add my iTunes files to My Library - this I understand. However, I don't want every file I download with Limewire to be saved to iTunes.

Meant to add that if I look in the folder .NetworkShare, all I see are Limewire versions going back to 4.18.3 (I'm using 5.1.2). Do I save files to this folder and then add it to My Library along with iTunes? There is only an Incomplete folder showing, not a Saved folder as indicated at the top of this post.

I was messing about with Tools>Options>Download and somehow changed my "Save downloads to:" folder.

I attempted to find something like limewire/library but cannot see it.

What is now the default download/saving folder for Limewire please?
