Abstract: Provided is a method for pre-loading content data. The method includes: acquiring a download speed; determining target content data in response to the download speed being less than a first speed threshold and a trigger event occurring, wherein the trigger event is configured to trigger pre-loading of the target content data, and the first speed threshold is determined based on corresponding play data in different speed ranges, the play data including at least one of a play amount or a lag rate; and loading the target content data.

Abstract: Provided in embodiments of the present application are a junk feature acquisition method, an apparatus, a server and a readable storage medium. The method is used on a first server, and the method comprises: obtaining storage paths to be analyzed; storage paths to be analyzed being: a storage path of a file corresponding to an application (app) installed on an electronic device; filtering out a target storage path out of the storage paths to be analyzed, the target storage path comprising: a storage path matching a file feature of a non-junk file in a pre-determined white list; making a storage path obtained by filtering into a junk feature. Using a method provided in an embodiment of the present application to acquire a junk feature can increase junk feature acquisition effectiveness and decrease labor consumption.
