The setenv command sets the UltraDefrag specific environment variables according to the user preferences:

C:\Program Files\UltraDefrag>set UD_EX_FILTER
Environment variable UD_EX_FILTER not defined

C:\Program Files\UltraDefrag>setenv

C:\Program Files\UltraDefrag>set UD_EX_FILTER
UD_EX_FILTER=*system volume information*;*temp*;*tmp*;*recycle*;*dllcache*;*ServicePackFiles*;*Windows.old*;*.log

The setenv command is part of the UltraDefrag Supplementary Scripts. Download the scripts and put them to the installation directory of UltraDefrag to be able to use the command.

Please note, as the setenv command is a batch script, you have to use the system call command to call it from your batch scripts:
