Smartware after rebuild concern/question

I have the WD Passport and used the Passport to automatically save files from the laptop using the Smartware.

I had Win7 32bit installed before the Great Cleaning. After the Great Cleaning, the laptop is now Win7 64bit.

If I install Smartware, will my existing folders and files on the Passport remain intact? (if they are moved into another folder prior to software install)

I do not want to lose anything!

It should not be an issue, the software should leave the data of the old back intact and create a new backup.
