ProjectReactor allows the storage of documents in a project. Documents may optionally be tagged to a deliverable. The number and size of documents that may be stored is defined by your account. Each acount type specifies a different storage allowance.
Documents may be displayed in a flat list or as a tree. To display documents in a tree structure, enter a value in the 'Virtual Path' field, with the tree hierarchy seperated by backslashes. For example: "Top Level\L1\L2\L3"
Files are physically stored in Amazon's S3 file store and ProjectReactor keeps some metadata about the file and how it fits into the project. When a file is downloaded from ProjectReactor, ProjectReactor creates a temporary URL that allows access to the file inside S3 for 5 minutes.
