A computing system may perform a method that involves receiving, from a first computing device, a request for a file, where the request identifies at least one user who has access to the file and includes information indicative of the file. The method further includes identifying, based at least in part on the received request, the file within a repository of files, sending, to a second computing device, a first indication of the request to access the file, receiving, from the second computing device, a second indication that the file is to be made accessible via the first computing device, and causing the file to be transferred from the repository to the first computing device.
