Methods, systems, and non-transitory computer readable storage media are disclosed for generating a customized organizational structure prior to uploading content items to a remote storage. For example, in one or more embodiments, the disclosed system identifies a set of content items to host on a remote storage and generates a visual representation of an organizational structure to be used for the content items at the remote storage. The system detects interactions modifying the organizational structure and provides the customized organizational structure to the remote storage prior to transmitting the content items. The system then transmits the set of content items to the remote storage in response to a transmission initiation event, and the remote storage stores the content items according to the customized organizational structure. In one or more embodiments, the system also allows the organizational structure and uploading of content items to be performed using different applications.
