Location of Cisco VPN client profile configuration file (.pcf file) on Mac OS X

If, like me, you arrived here looking for the Cisco AnyConnect profile location, I found my config information at

/opt/cisco/anyconnect

I wanted this to be a comment on the accepted answer, but I bumped into the rep limit. If a mod wants to move this to the comments of the accepted answer, be my guest!

Open a terminal and search for it (go ahead to the next line if the previous one doesn't find anything):

find ./Library -name '*.pcf'
find . -name '*.pcf'
find / -name '*.pcf'

If you don't find anything, check the Library folder inside your home directory. I think the Cisco client might import the settings and store it in some other format (or at least in another file) inside the Library or Library/Preferences folder.
