moving a library

I've built or downloading a number of components in SW andplaced them in my library. I save them in a directory called "CWLibrary", and in options/models/ "Save the models Circuitworkscreates to these folders" dialog box I specified my CW Libraryfolder location. Circuitworks still appears to keep the library in
C:\Documents and Settings\All Users\ApplicationData\SolidWorks\circuitworks\components as well?
I'd like to make my library portable because I work at home &at the office. I've tried copying my library directory from onecomputer to another, but some of the parts transfer & somedon't. Do I need to copy both of these directories & keep trackof them? How can I make this easy? Is it necessary to use theExport Data command?SolidworksCircuitworks
