It is now possible to associate folders with metadata records. This allows you to attach metadata to folders and find folders based on queries over the metadata. For example, it is now possible to upload files for an experiment and store files from a particular sample in a single folder. When you create a metadata model to capture all relevant information about the sample and point this record at the folder, the folder is findable by querying over the metadata.
For example, the screenshot below returns the results for any files or folders that are associated with a metadata record of type Sample* which in turn is related to a subject** of a particular strain.
