Abstract

In a network communication system, data is exchanged between a source computer and a destination computer via a file server. The source computer is a network multifunction product and includes an uploading unit that uploads a file to the file server; and a URI sending unit that sends a Universal Resource Identifier (URI) of the file to the destination computer by e-mail. The destination computer is also a network multifunction product and includes a table that holds security information that is required to access to the file; a URI receiving unit that receives the URI; and a downloading unit that downloads the file from the file server using the security information that corresponds to the URI.

Claims

1. A network communication system comprising a file server, a source computer, and a destination computer, wherein the source computer is a network multifunction product and includes

an uploading unit that uploads a file to the file server;

and

a URI sending unit that sends a Universal Resource Identifier (URI) of the file to the destination computer by e-mail.

2. The network communication system according to claim 1, wherein the source computer further includes a folder creating unit that creates a folder to store the file on the file server.

3. The network communication system according to claim 2, wherein a name of the folder is a combination of a predetermined prefix, a physical address of the source computer, and date when the file is uploaded to the file server.

4. The network communication system according to claim 1, wherein the URI is different from a URI to which the file is uploaded by the uploading unit.

5. The network communication system according to claim 1, wherein the destination computer is a network multifunction product and includes

a table that holds security information that is required to access to the file;

a URI receiving unit that receives the URI; and

a downloading unit that downloads the file from the file server using the security information that corresponds to the URI.

6. The network communication system according to claim 5, wherein the security information includes a user ID and a password.

7. The network communication system according to claim 1, wherein

the source computer further includes a storage period sending unit that sends a storage period, which is a period for which the file is to be stored, to the file server, and

the file server deletes the file when the storage period of the file has expired.

8. A network multifunction product that is connected to a file server in a network communication system, comprising

an uploading unit that uploads a file to the file server;

and

a URI sending unit that sends a Universal Resource Identifier (URI) of the file to a destination computer by e-mail.

9. The network multifunction product according to claim 8, further comprising a folder creating unit that creates a folder to store the file on the file server.

10. The network multifunction product according to claim 9, wherein a name of the folder is a combination of a predetermined prefix, a physical address of the source computer, and date when the file is uploaded to the file server.

11. The network multifunction product according to claim 8, further comprising:

a table that holds security information that is required to access to the file;

a URI receiving unit that receives the URI; and

a downloading unit that downloads the file from the file server using the security information that corresponds to the URI.

12. The network multifunction product according to claim 11, wherein the security information includes a user ID and a password.

13. The network multifunction product according to-claim 8, further comprising a storage period sending unit that sends a storage period, which is a period for which the file is to be stored, to the file server, wherein

the file server deletes the file when the storage period of the file has expired.
