 The main difference between a `FilePath` and a [`java.io.File`](https://docs.oracle.com/javase/8/docs/api/java/io/File.html) is that a `FilePath` caches the `VirtualFile` corresponding to the path, so it can be retrieved without doing a VFS search.
 
 To create instances of `FilePath`, the [`VcsContextFactory`](upsource:///platform/vcs-api/src/com/intellij/openapi/vcs/actions/VcsContextFactory.java) API is used.

+It can be accessed as `PeerFactory.getVcsContextFactory()`.
 
 `FilePath` representing paths in a VCS repository, rather than local paths, are created using `VcsContextFactory.createFilePathOnNonLocal()`.
 The `FilePath.isNonLocal()` method returns `true` for such files.
