Unisphere for VMAX BTP Files

Hi

i have Unixphere for VMAX version 1.1.0.5, i am looking for the BTP or TTP files in this path F:\EMC\SYMAPI\stp\spa\DMF_10.60.16.70 but this folder is empty

or where are the BTP files created?, iam a little bit confuse if the BTP files are created by default or i need to create them on demand, i took a look to the unisphere for vmax product guide i there is an option to create btp files, but those btp files are just for the last 4 hours.

i'll appreciate your help on this

Best regards
