Abstract

Methods 300 and systems 100 are provided for managing files unzipped from a zipped archive file which may have been received, for example, as an email attachment. In response to an undo-unzip command from a user, a manifest associated with the archive is accessed that includes information for identifying the files previously unzipped from the archive file. The undo-unzip command causes the unzipped files to be located and deleted. If unzipped files are found which have been edited or modified since being decompressed, they may be selected to avoid deletion.

Claims

1. A method of managing unzipped files from an archive, the method comprising:

receiving an undo-unzip command;

accessing a manifest associated with the archive;

identifying the unzipped files based on information in the manifest; and

deleting the unzipped files in response to the receiving of the undo-unzip command.

2. The method of claim 1, further comprising:

creating the manifest prior to the receiving of the undo-unzip command and in response to receiving an unzip command.

3. The method of claim 2, wherein the manifest comprises a list of decompressed files from the archive, locations where each of the decompressed files are stored, and a checksum for each of the decompressed files.

4. The method of claim 1, wherein all files from the archive are deleted in response to the receiving of the undo-unzip command.

5. The method of claim 2, wherein the archive is a first archive, the method further comprising:

deleting the first archive file in response to receiving the unzip command; and

creating a second archive file in response to the receiving of the undo-unzip command;

wherein the second archive file comprises zipped versions of the unzipped files from the first archive.

6. The method of claim 1:

wherein the unzipped files are unmodified files from the archive; and

wherein modified files from the archive are not deleted.

7. The method of claim 1, wherein the archive was received as a self-executing zipped email attachment file.

8. The method of claim 1:

wherein the unzipped files are stored in a memory which also stores a plurality of other files; and

wherein said undo-unzip command does not affect said plurality of other files.

9. An archive management system comprising:

a user input device configured to receive an undo-unzip command;

a memory suitable for storing unzipped files and a manifest associated with an archive; and

a processor configured to identify the unzipped files based on information in the manifest and control the memory to delete the unzipped files in response to the undo-unzip command.

10. The system of claim 9, further comprising:

a data interface configured to receive an email communication via a network;

wherein the archive is received by the system in the email communication via the network.

11. The system of claim 9, wherein the manifest comprises a list of decompressed files from the archive, locations where each of the decompressed files are stored, and a checksum for each of the decompressed files.

12. A computer readable media embodying a method of managing unzipped files from an archive, the method comprising:

receiving an undo-unzip command;

accessing a manifest associated with the archive;

identifying the unzipped files based on information in the manifest; and

deleting the unzipped files in response to the receiving of the undo-unzip command.

13. The computer readable media of claim 12, further comprising:

creating the manifest prior to the receiving of the undo-unzip command and in response to receiving an unzip command.

14. The computer readable media of claim 13, wherein the manifest comprises a list of decompressed files from the archive, locations where each of the decompressed files are stored, and a checksum for each of the decompressed files.

15. The computer readable media of claim 12, wherein all files from the archive are deleted in response to the receiving of the undo-unzip command.

16. The computer readable media of claim 13, wherein the archive is a first archive, the method further comprising:

deleting the first archive file in response to receiving the unzip command; and

creating a second archive file in response to the receiving of the undo-unzip command;

wherein the second archive file comprises zipped versions of the unzipped files from the first archive.

17. The computer readable media of claim 12:

wherein the unzipped files are unmodified files from the archive; and

wherein modified files from the archive are not deleted.

18. The computer readable media of claim 12, wherein the archive was received as a self-executing zipped email attachment file.

19. The computer readable media of claim 12:

wherein the unzipped files are stored in a memory which also stores a plurality of other files; and

wherein said undo-unzip command does not affect said plurality of other files.
