File folder transmission on network

An apparatus for transmitting a file folder from a sending end to a receiving end, the apparatus comprising:

• one or more processors;
• memory;
• a file directory management module stored in the memory and executable by the one or more processors that is adapted for generating a directory structure file of the file folder, the directory structure file having properties including size of the file folder, paths and path lengths of files in the file folder, wherein generating the directory structure file comprises traversing the file folder and computing the properties of the directory structure file;
• a file folder transmission operation logic module stored in the memory and executable by the one or more processors that is adapted for determining files in the file folder that need to be transmitted from the sending end to the receiving end according to the directory structure file;
• and
• a network transmission module stored in the memory and executable by the one or more processors that is adapted for sending the directory structure file from the sending end to the receiving end, and for transmitting the files in the file folder that need to be transmitted to the receiving end.

One or more storage devices having stored thereupon a plurality of instructions that, when executed by a processor, causes the processor to perform acts comprising:

• generating a directory structure file of a file folder, the directory structure file having properties including size of the file folder, paths and path lengths of files in the file folder, wherein generating the directory structure file comprises traversing the file folder and computing the properties of the directory structure file;
• sending the directory structure file from a sending end to a receiving end;
• determining files in the file folder that need to be transmitted from the sending end to the receiving end according to the directory structure file;
• and
• transmitting the files in the file folder that need to be transmitted to the receiving end.
