Method of transferring file
First Claim
1. A method of transferring a file by two simultaneous data transmissions, said method comprising the steps of:
- transmitting data in a forward direction starting from a first specified position to a bottom in the file; and
transmitting data in a backward direction starting from a second specified position to a top in the file.

Abstract
A method of transferring file of the present invention by the two simultaneous data transmissions comprises the steps of transmitting data in a forward direction starting from a first specified position to a bottom in the file, and transmitting data in a backward direction starting from a second specified position to a top in the file. And a method of transferring file in FTP of the present invention comprises the steps of establishing a control connection, establishing multiple data connection, dividing a file into segments from each arbitrary point in the file, transferring segments through each of the multiple data connections, respectively, and synthesizing file from the segments transferred through the multiple data connections.

8. A method of transferring a file comprising the steps of:
-
establishing a first connection by which a data is transmitted in a forward direction started from a top of a file to be transferred, and at the same time, establishing a second connection by which a data is transmitted in a backward direction started from a bottom of the file; and
establishing a third connection by which a data is transmitted in a backward direction started from a certain point around an effective center area of the file, and at the same time, establishing a fourth connection by which a data is transmitted in a forward direction started from the point around the effective center area of the file.

9. A method of transferring a file comprising the steps of:
-
establishing a first connection by which a data is transmitted in a forward direction started from a top of a file to be transferred;
at the same time, establishing a second connection by which a data is transmitted in a backward direction started from a bottom of the file;
establishing a third connection by which a data is transmitted alternatively in a forward direction and a backward direction at every specific unit data from a certain point around the effective center area of the file.
