One or more embodiments of a thumbnail caching system dynamically provide a thumbnail cache of digital content items (e.g., photos, videos, audio) to a user on a client device. In particular, the thumbnail caching system provides a thumbnail cache of a digital content collection to a client device such that the thumbnail cache does not exceed a threshold storage limit for the client device. In addition, the thumbnail caching system intelligently adjusts the thumbnails within the thumbnail cache to keep the size of the thumbnail cache within the threshold storage limit irrespective of the number of digital content items stored or added to the digital content collection. Further, the thumbnail caching system can dynamically adjust the size of the thumbnail cache in response to a user adding or removing external data to the client device.

Providing a dynamic digital content cache

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.
