someone once asked me: "where to find apache folder on linux server" my answer was:

if you have apache on a linux server and you want to know where to find the apacher folder that will depend on your distribution. for example, i have a red hat fedora core 7 unix server and if you want to find the location of the apache installation here are some

/etc/httpd/
has the following files and directories
conf conf.d logs modules run

if you want to know where the error files are:
/var/log/httpd

so what file are you looking for?

also, by the way, in linux, there are not folder, they are called directories. windows called them folders.
