Abstract: The present invention relates to the field of computer technologies, and provides a method and a device for opening an object and a storage medium. The method for opening an object includes: monitoring an open instruction of the object; acquiring a recent use coefficient of the object if the open instruction is detected; and prompting the user to confirm the open instruction if the recent use coefficient meets a preset condition when compared with a preset threshold, and opening the object after receiving the confirmation on the open instruction from the user. With the present invention, different open processes are respectively performed according to the historical opening conditions of various objects, to effectively prevent the open of the object by a misoperation.
