I need help finding my search term history, that is the terms I have successfully used in the past to find the files I'm looking for. I am using LimeWire V. 4.14 on a XP machine. Any ideas on where the history is hidden???

There's no search term history saved. It ends once your LW session ends (ie when you shut down LW).

In older versions it was saved in the limewire.props file. Did they get rid of that. I can't seem to find it.

Sorry about that...I had no idea that a history of search terms was saved

Have a look in C:\Documents and Settings\your username\Application Data\LimeWire...that's where I found the file.
The App Data folder's hidden by default, so make sure to show hidden files & folders first.
