I agree with Myrnice about trying it in TMG. If you have not purchased either program yet, go to TMG. However, if you have UFT and want to stick with it, there is a procedure to importing R3 filesinto UFT.
From the File menu, choose open. Select Roots III Basefile from the File Type list. Select the drive and directory where the DCB file is found. Choose the options you want. (must be careful here on options, but I believe you can use F1 or help).
Our group has Roots III books available, if you need anything like that.
