Abstract

Disclosed are methods and systems for compressing data communicated in an electronic message. Files attached to an electronic communication are compressed based on an examination of the file type; and an identification of an alternative compressed file type. Accordingly, the first (original) file type is compressed into a second preferred, compressed file type for the purpose of streamlining the package to be delivered in the communication.

Claims

1. A method for compressing data in a communication transmitted in an electronic messaging system, comprising:

as part of a process of carrying out a request to transmit an electronic messaging communication, providing a prompt offering to compress content of the electronic messaging communication if the content of the electronic messaging communication is determined to be suitable for compressing, the determination being based on the type of content and whether a size of the content is larger than a threshold value, wherein the prompt provides additional information to assist the composer in deciding whether to accept or decline the compression offer and is offered only when the size of the content is larger than the threshold value;

compressing the content if the composer accepts the compression offer; and

transmitting the electronic messaging communication.

2. The method according to claim 1, further comprising:

comparing file types of attachments within the electronic messaging communication with a listing of compressible file types.

3. The method according to claim 1, wherein compressing the content of the electronic messaging communication comprises compressing an original attachment file from a first file type into a compressed attachment file of a second file type.

4. The method according to claim 1, further comprising creating a communication that replaces the original attachment file with the compressed attachment file for transmission to a recipient.

5. The method according to claim 1, wherein the electronic messaging communication is at least one of an e-mail and an instant message.

6. The method according to claim 1, wherein a transmitted electronic messaging communication contains an indication to a recipient that the attachment files are compressed from their original content.

7. The method according to claim 1, wherein the additional information comprises a comparison of characteristics of an original attachment file against a proposed compressed version of the attachment file.

8. The method according to claim 7, wherein the characteristics comprise an estimated file size of the compressed version.

9. The method according to claim 7, wherein the characteristics comprise an estimated time to download the electronic messaging communication by a recipient of the electronic messaging communication.

10. The method according to claim 7, wherein the characteristics comprise estimated degradation characteristics of the compressed version.

11. The method according to claim 1, further comprising:

after transmission of the electronic messaging communication, receiving a notification that the electronic messaging communication was undeliverable due to the size of the electronic messaging communication, the notification containing an acceptable size limit for the electronic messaging communication; and

providing a prompt offering to compress the electronic messaging communication below the acceptable size limit and re-transmit the electronic messaging communication.

12. A machine-readable storage medium, having stored thereon data and instructions tangibly embodied in the storage medium so as to be executable by a processor and when executed, cause the processor to perform:

as part of a process of carrying out a request to transmit an electronic messaging communication, providing a prompt offering to compress content of the electronic messaging communication if the content of the electronic messaging communication is determined to be suitable for compressing, the determination being based on the type of content and whether a size of the content is larger than a threshold value, wherein the prompt provides additional information to assist the composer in deciding whether to accept or decline the compression offer and is offered only when the size of the content is larger than the threshold value;

compressing the content if the composer accepts the compression offer; and

transmitting the electronic messaging communication.

13. The machine-readable storage medium according to claim 12, further comprising:

comparing file types of attachments within the electronic messaging communication with a listing of compressible file types.

14. The machine-readable storage medium according to claim 12, wherein compressing the content of the electronic messaging communication comprises compressing an original attachment file from a first file type into a compressed attachment file of a second file type.

15. The machine-readable storage medium according to claim 12, further comprising instructions for creating a communication that replaces the original attachment file with the compressed attachment file for transmission to the recipient.

16. The machine-readable storage medium according to claim 12, wherein the electronic messaging communication is at least one of an e-mail and an instant message.

17. The machine-readable storage medium according to claim 12, wherein the additional information comprises a comparison of characteristics of an original attachment file against a proposed compressed version of the attachment file.

18. The machine-readable storage medium according to claim 17, wherein the characteristics comprise an estimated file size of the compressed version.

19. The machine-readable storage medium according to claim 18, wherein the characteristics comprise an estimated time to download the electronic messaging communication by a recipient of the electronic messaging communication.

20. The machine-readable storage medium according to claim 18, wherein the characteristics comprise estimated degradation characteristics of the compressed version.
