Last updated on May 19, 2024

The clearenv command clears the UltraDefrag specific environment variables set by the setenv command:

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

C:\Program Files\UltraDefrag>clearenv

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

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

call "%UD_INSTALL_DIR%\clearenv.cmd"
