Often, the WET software will not automatically transfer data in drives/partitions other than “C”. In this scenario, the best approach is to use the Bravura Easy Computer Sync software, which will allow you to drag and drop folders between machines manually, allowing you to migrate data from other partitions.
A few additional notes:
-Many people choose to perform the WET process first, then use the Bravura software afterwards to copy things in custom locations that WET did not automatically transfer.
-You should have received an email after purchase with a license key for the Bravura software. If you did not receive this, please provide your Amazon Order ID and we’ll be glad to look up your order and resend the corresponding email.
