Does .profile get used by a putty session also?

I was reading

Typing <sic: PATH> every time I start PASE is very cumbersome.
Fortunately, you don't have to type it every time! Instead, you can put
the command into a special file named .profile, and the command will
automatically be run every time you start a PASE shell. For example, I can
type the following within PASE.

echo
"PATH=$PATH:/QOpensys/usr/local/bin:/usr/local/Zend/Core/bin:/usr/local/mysql/mysql/bin"

$HOME/.profile

My question is this: Will that .profile also be used by a putty session?

Another question is where do I find that .profile file?
I did DSPUSRPRF ROB
Home directory . . . . . . . . . . . . . . : /FTP
WRKLNK '/FTP/*'
There's nothing that which begins with a period.
