Project
A project is a directory that keeps everything that makes up the application. A typical project has a set of settings and one or several modules. The project provides a mechanism to express dependencies between modules and stores modules' shared configuration.
.idea Directory
The .idea directory is used by IntelliJ to store project settings metadata, and it is collocated with the project. It lives by default under the project's root. It contains the following file:
User-Specific Settings
workspace.xml
Stores user-specific settings.
tasks.xml
User Dictionaries
Maintained in .idea/dictionaries/username.xml.
shelf
datasources.xml
In IDEA 13 or earlier, datasources.xml contains user passwords.
libraries
All XML files under .idea/libraries will be generated by the Gradle or the Maven project.
gradle.xml
Gradle settings.
vcs.xml
These are some recommendations on what to share and what not to share in a SVC system. The article applies to Git, but the rules are generally valid:
Project Settings
The project settings apply to the current project. They are stored together with other project files in the .idea directory in an XML format. Project settings are VCS settings, SDKs, code style, spellchecker settings, compiler output, libraries. All these setting are available to all the modules of the project.

Module
A module is a logical group of source code and resources within a project.
The module has an .iml file that keeps the internal representation of the module settings. The module is also associated with a module content root directory, which stores the source code, tests and resources. The .iml file and the module content root are not tied, they can exists in different locations on the file system.
.iml File
The .iml file keeps the internal representation of the module settings.
Module Settings
Module settings apply only to one module and they are stored in the module's .iml file.
As part of its settings, a module can have an SDK and a language level that are different from those configured for the enclosing project. A module can also have its own libraries. A module can also carry a specific technology or framework.

Grouping Modules
Settings
There are three type of settings in IntelliJ IDEA: module settings, project settings and global settings.
Global Settings
Global settings apply to all projects of a specific installation of IntelliJ IDEA. Such settings include IDE appearance, themes, color schemes, the set of installed and enabled plugins, debugger settings, global inspection profile.
