Drupal comes with a default.settings.php file in the sites/default
directory. The installer will create a copy of this file filled with
the details you provide through the install process, in the same
directory. For Drupal to be able to create the file, you need to

Consider creating a "files" subdirectory in your Drupal installation
directory. This subdirectory stores files such as custom logos, user avatars,
and other media associated with your new site. The sub-directory requires
"read and write" permission by the Drupal server process. You can change
the name of this subdirectory at "administer > site configuration > file
system".
Determine whether the default "files" directory is the right location for your
file system path. Drupal uses the location specified in the file system path
to store files attached to site content, theme-specific logos, user avatars, and
some temporary files. On some installations, it may be necessary to modify
the file system path, especially in large or multi-site configurations. See the
files/README.txt file for more information about setting the file system path.

The files directory is the default file system path used to store
all uploaded files, as well as some temporary files created by Drupal. To
successfully install Drupal, the files directory must exist and be
writable by the web server process.
After installation, the settings for the file system path may be modified
to store uploaded files in a different location. Ensure that this new
location exists, is accessible, and is writable by the web server process.
The file system path settings can be accessed by selecting these menu items
from the Navigation menu:
administer > site configuration > file system
You may wish to modify the file system path if:
* your site runs multiple Drupal installations from a single codebase
(modify the file system path of each installation to a different
directory so that uploads do not overlap between installations);
* your site runs a number of web server front-ends behind a load
balancer or reverse proxy (modify the file system path on each
server to point to a shared file repository); or,
* your site policies specify that all site-related files are stored
under the sites directory in order to simplify backup and restore
operations (modify the file system path to point to a newly-created
directory underneath sites).
Changing the file system path after files have been uploaded may cause
unexpected problems on an existing site. If you modify the file system path
on an existing site, remember to copy all files from the original location
to the new location.
