Systems and methods for providing previews of files stored in an online content management system with collaboration environment and permitting a user to annotate the previews are disclosed. The system further tracks the frequency of access of content in previewed documents and provides a visual representation of the frequency with which sections in a document was viewed.

Extended applications of multimedia content previews in the cloud-based content management system

Systems and methods for providing improved content previews of files stored in an online content management system with collaboration environment are disclosed. An optimized PDF rendering engine is used to reproduce the appearance of previewed PDF documents. The present disclosure includes a method of evaluating the available system tools for converting files from an existing format to a target format to determine the optimum tool(s) to use for the conversion process of a file.

Enhanced multimedia content preview rendering in a cloud content management system

Techniques are disclosed for reducing database workload in implementing selective subfolder synchronization in a cloud-based environment. In one embodiment, a method comprises, in response to a selection, from a user, of a first synchronization state of a first folder in the workspace, synchronizing content of the first folder in the workspace with a corresponding folder on devices of a user (and collaborators) based on the first synchronization state. The workspace is shared among the user and one or more collaborators of the user. In some embodiments, the method further comprises determining the first synchronization state of the first folder based on synchronization states of one or more folders, other than the first folder, that are related to the first folder. The entries can be configured to identify hierarchical relationships between the one or more folders and the first folder on a per-user basis.

Server side techniques for reducing database workload in implementing selective subfolder synchronization in a cloud-based environment

System and methods for determining if a preview of a file uploaded to a web-based collaborative environment is likely to be requested. For a file that is likely to be previewed, the system pre-converts the input format of the file to a target format suitable for providing the preview to minimize the time a user waits to be presented with the preview after making the request. The present disclosure includes a method of determining whether an intermediate format of a file generated during the conversion of an input format to the target format should be stored to be used later or discarded.

Preview pre-generation based on heuristics and algorithmic prediction/assessment of predicted user behavior for enhancement of user experience

Systems and methods for providing content previews of files, including video files, stored in an online content management system with collaboration environment are disclosed. Permission to view a preview of a file is determined based upon access permissions associated with the file and/or workspace in which the file is stored and the access level of the requesting user. The system can also provide a progress indicator indicating the approximate time remaining to process the file for previewing based upon averages of times for processing previous files having similar attributes. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for downsampling a video file to decrease the processing time for providing a preview.
