A computer readable medium including a program containing computer-executable instructions for performing the method for providing a continuous downloading service of large size content through a wireless network comprising a mobile terminal and a content server, wherein the program performs the method comprising:

• receiving a request from the mobile terminal for downloading content, wherein the content comprises a plurality of individual files;
• generating and transmitting a first package list for the requested content to the mobile terminal;
• downloading the individual files included in the first package list to the mobile terminal;
• if the download is suspended, receiving i) a request for a continuous download of the content and ii) a second package list from the mobile terminal;
• extracting a third package list for the requested content, wherein the third package list is the latest package list of the requested content stored in the content server;
• comparing information of individual files in the second package list and the third package list;
• generating a first required file list including at least one individual file having different information in the second package list and the third package list;
• transmitting the first required file list to the mobile terminal;
• receiving one of i) size data of a temporary file previously downloaded to the mobile terminal and ii) a second required file list including at least one file from the mobile terminal;
• and
• downloading one of i) the remaining portion of the temporary file and ii) the at least one file of the second required file list to the mobile terminal.
