Spaces and Subspaces
You can create a hierarchy of nested folders (
Spaces and 
Subspaces) for new documents, and optionally save them as Shortcuts in Navigation.
Five levels of nested subspaces and up to 250 artifacts within each of them are officially supported.
Plan and create your Space and Subspace hierarchy before creating documents to avoid any move restrictions.
Permissions change when creating a new Subspace within a Space. If you create a Subspace within a Space, or Move a Space/Subspace from another Space, they do not inherit the Subversion repository's restrictions, or permissions from their new parent. If you want to restrict access to a newly created Subspace, you need to work with an an administrator to remove the SVN access rights and create a custom rule for permissions (see Configure user Permissions: Define permissions for Artifact Sets).
When creating documents in Polarion for the first time, it's a good idea to plan out how you would like to organize them beforehand. Unlike Word documents, Live Documents and Live Reports are integrated with a vast array of possible widgets, potentially thousands of Work Items, and in the case of Live Documents, a powerful version history.
This diversity of integrated external content can lead to move restrictions, so its a good idea to organize your Spaces and Subspaces from the start, to avoid any potential move restrictions.
You can move LiveDoc Documents once they're created, but you cannot move Live Report, Info or Classic Wiki pages.

In Navigation, click
Documents and Pages.Click

Space to appear in.(If you've already created a
Subspace within a Space, then the hierarchy appears within the list control.)
Click Create.
The new
Space appears in the navigation bar's Space hierarchy.
Now when you create a new Live Document, Live Report, Info Page, or Classic Wiki Page , you can select any
Space or Subspace in the Space list.
Live Documents can also be moved to a
Space or Subspace.
Hierarchical spaces created in the Polarion do not actually create physical nested folders within the repository.
