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.
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.)
