###How to get a file module?
```final Module currentModule = fileIndex.getModuleForFile(virtualFile);```
###How to get a module file index?
Information about model roots can be accessed via the class
[ModuleRootManager.java] (https://github.com/JetBrains/intellij-community/blob/master/platform/projectModel-api/src/com/intellij/openapi/roots/ModuleRootManager.java),
for example, an instance of
[ModuleFileIndex.java] (https://github.com/JetBrains/intellij-community/blob/master/platform/projectModel-api/src/com/intellij/openapi/roots/ModuleFileIndex.java)
can be obtained, which is analogical to the
[ProjectFileIndex.java] (https://github.com/JetBrains/intellij-community/blob/master/platform/projectModel-api/src/com/intellij/openapi/roots/ProjectFileIndex.java)
but in the scope of a module
```ModuleRootManager.getInstance(currentModule).getFileIndex()```
##Changing the project structure
Utility classes which can be used for modifying a project structure can be found in the package
[projectModel-impl.openapi] (https://github.com/JetBrains/intellij-community/blob/master/platform/projectModel-impl/src/com/intellij/openapi).
It's
[roots] (https://github.com/JetBrains/intellij-community/blob/master/platform/projectModel-impl/src/com/intellij/openapi/roots/)
subpackage contains instances and utilities meant to work with project and module source roots, including
[ModuleRootModificationUtil.java] (https://github.com/JetBrains/intellij-community/blob/master/platform/projectModel-impl/src/com/intellij/openapi/roots/ModuleRootModificationUtil.java)
and
[ProjectRootUtil.java] (https://github.com/JetBrains/intellij-community/blob/master/platform/projectModel-impl/src/com/intellij/openapi/projectRoots/impl/ProjectRootUtil.java)
