"Lanwench [MVP - Exchange]"
This isn't something built in to any computer by default - you could
have G set up as pretty much anything.
Perhaps the documentation means to say that for G: you are to read
<your CD-ROM drive> or something. Regardless, you need to check with
the people who support the app you are using - this isn't something
that anyone else could answer.
The other option is that whoever created the module did not check
it out completely and it still has a link pointing to somewhere on
"their" G drive (not yours). If that is the issue, whomever created
the "module" needs to resolve the issue of where the thing is you are
supposed to open.
