The Package in Detail¶
TYPO3 Folders and Files¶
The following files and folders are part of the TYPO3 Source package.
- contains the TYPO3 source code, files, images and scripts distributed with TYPO3.
- the main script for the website Frontend
- contains an example configuration for Apache web servers, which
can improve performance. It is not used by default. To activate it,
copy the file to
.htaccessin your document root.
- describes what has changed in the TYPO3 Source since the last major version. Read this carefully if you are going to update your system!
- contains system requirements and a short installation how-to.
All these files are part of the TYPO3 Core. You should never change them and you can make them write-protected, if you like! They are the ones you must upgrade when you install a new version of TYPO3.
Site specific Folders and Documents¶
The following files and folders will be created during the installation of TYPO3:
- contains your site assets and files, local to the website.
You can e.g. put templates, user uploads, external scripts and
images here. By default this folder is used to store files, which
have been uploaded in the TYPO3 Backend (
fileadmin/is configured as the first default storage).
fileadmin/must be writable for the web server user.
- contains configuration, extensions and translations for the local site.
- will hold the local extensions available for this installation. Can be managed through the Extension Manager.
- will hold translations for the TYPO3 Backend of this installation.
- is the main configuration file of your installation and the one the customized values of all the Install Tool options get written to. It has to be writable and will be updated automatically by the Install Tool and the Extension Manager. You can edit this file manually, but make sure you keep the PHP syntax working.
- contains information about the extensions, which are available in your system.
- is an additional configuration file, which is executed on every
request after the
LocalConfiguration.phphas been loaded. It can be used to manipulate the configuration of
$GLOBALS['TYPO3_CONF_VARS']. This file is not created automatically; create it, if you need it.
- will be empty at the beginning. But gradually temporary files will appear here. The directory must be writable for the web server user.
- (deprecated) contains folders used to store documents attached to
database records, hence must be writable by the web server. This folder
is used for compatibility reasons with older TYPO3 releases and
extensions. Newer extensions and the TYPO3 core do not use this
folder anymore; instead files should be managed by the File
Abstraction Layer inside the default storage (
