Abstract: A computer-implemented method, computer system, and computer program product for recommending a target location for relocating a file are disclosed. In the method, a source path of a file is obtained. Then, a target starting directory in a target directory system to which the file is to be relocated is determined based on the source path. A directory model representing a subordinated directory system of the target directory system is determined. The directory model comprises at least one path starting with the target starting directory. Then, a similarity of the at least one path in the directory model with respect to the source path is determined. Next, at least one candidate path from the at least one path is recommended based on the similarity.

Abstract: A tool for managing message notifications in a computing environment includes a computer determining a user receives a notification of a first message received in a collaboration application on a computing device of the user, and determining a topic for the first message. The computer then determines whether the user suppresses the notification of the first message, and if so, the computer stores the topic for the first message associated with an indication the user suppressed the notification for the collaboration application. The computer further determines a second message is received, determines a topic of the second message, and then determines whether the user previously suppressed the topic of the second message. If the user previously suppressed the topic of the second message, the computer suppresses a notification for the second message.

Abstract: A touch panel with a fingerprint identification function includes a cover plate, a mask layer, a flexible substrate, and a fingerprint sensing array. The mask layer is disposed on the cover plate for defining an operating region and a non-operating region of the touch panel. The flexible substrate is disposed on the mask layer and at least in the non-operating region. The fingerprint sensing array is directly disposed on the flexible substrate in the non-operating region. Through the configuration that the fingerprint sensing array is disposed on the flexible substrate, the distance between the fingerprint sensing array and a user's fingers is reduced, thereby increasing the sensitivity of fingerprint identification.
