The present disclosure is directed toward systems and methods that efficiently and effectively generate and utilize collections of content items. For example, systems and methods described herein generate a collection content item including one or more content item references. In one or more embodiments, the collection content item can include content item references for content items located internally or externally, with granular levels of permissions settings and version controls. Additionally, in response to a detected selection of a content item reference, systems and methods described herein generate a rendering of the associated content item that can be viewed regardless of any third party software installed on the viewing client computing device.

Generating and modifying a collection content item for organizing and presenting content items

Aspects of the subject technology relate to ways to avoid file duplication in a cloud storage service. In some aspects, a method of the technology includes steps for retrieving, via a computer network, one or more files from a first memory location, identifying a first signature and a second signature for each of the files, and storing the first signature and the second signature into a duplication reference list. In some aspects, the method further includes steps for analyzing files in a second memory location to identify duplicate files using the duplication reference list. Systems and computer-readable media are also provided.
