See $DDS_ROOT/docs/design/persistence.txt General usage notes for FileSystemStorage:

• Start by calling Directory::create() to get a handle on a new or existing directory. All of its files and subdirectories must be managed by this library. The file and directory names will be encoded so the application doesn't need to be aware of filesystem limitations regarding special characters or length limits (for directory names).
• File names are limited to 150 characters, but directory names are unlimited.
• The get_*() functions always create the file/dir if it doesn't exist.
• The application must take care not to create two objects representing the same node in the filesystem (for example via get_file() and via iteration) because their state will not be kept consistent if one is modified.
• Locking is the responsibility of the application.
• These classes will throw std::runtime_error if there is a problem with the underlying file system (out of space, bad permissions, etc.) or other unexpected/irregular condition.
