You can save your preferences.txt file in your IDE folder by doing the following . . .
Edit the preferences.txt -
the one in the "lib" folder - under the IDE install.
Remove the comment mark before "settings.path=data". i.e.
# if you don't want settings to go into "application data" on windows
# and "library" on macosx, set this to the alternate location.
settings.path=data
This will put your user preferences.txt in the "data" folder in the IDE.
(You may have to make the "data" folder and copy a preferences.txt into it.)
