Abstract: Methods, apparatuses, and systems are provided for uploading a file in the field of computer technology. The method includes a router receiving a target file for uploading to a target server which is transmitted from a terminal; determining a feature value of the target file; obtaining a list of feature values of files for the target server, in which the feature value of each file stored in the target server is recorded; transmitting the target file to the target server, when the feature value of the target file is not in the list of feature values of files; and transmitting the feature value of the target file to the target server, when the feature value of the target file is in the list of feature values of files.

Abstract: A method for text selection includes: determining, in text for selection, a first display position of a start selection point and a first display position of an end selection point, wherein text between the start selection point and the end selection point is target text including at least one character; partitioning the text for selection into a plurality of text blocks based on semantic meaning; receiving a dragging operation corresponding to the start selection point or the end selection point; and changing, according to the dragging operation, the first display position of the start selection point or the first display position of the end selection point to a corresponding second display position in unit of a text block.
