Brian,
Thanks. However I am using the Norton Antivirus product.
The document shows how to remap the contents under "Program Files\Symantec\Symantec Endpoint Protection Manager".
Searches in Win XP registry did not pull anything relevant to a directory location.
Like you said, it is hard-coded in the product.
Kicked off the liveupdate and tried to figure out which directory it was writing to.
No luck.
The directory under C:\Prog Files\Norton Antivirus\ did not grow.
It was 50 MB while starting the liveupdate and remained constant.
Assumed to find anything in Doc & Settings\Downloads and did not find anything there either.
Long story short, I looked hard enough and cleared around 1 GB from old installs/ downloads and got around liveupdate download whatever it wanted.
Maybe you can still post the exact directory where Norton writes to on a win XP machine. My Norton version is 18.7.1.3.
Will help those who run into the same issue.
Thanks for your solution though.
I can see how it can be used to circumvent other software that locks in the C drive ;-)
Cheers.
