Abstract

Files to be installed on a computer system are streamed from an archive as the archive is being extracted directly to one or more final destination locations on the computer system.

Claims

1. A computer implemented method comprising:

launching an extraction process; and

extracting at least one file from an archive directly to one or more final file destinations on a computer system.

2. The computer implemented method of claim 1 wherein said extracting at least one file from an archive directly to one or more final file destinations on a computer system comprises:

registering a call back with an extraction engine;

launching said extraction engine, said launching causing said extraction engine to obtain an archive specified file destination for said at least one file from said archive, and to generate and send a call back;

receiving said call back from said extraction engine, said call back including an archive specified file destination for said at least one file;

looking up a key map specified file destination associated with said at least one file in a key map database;

determining whether said at least one file is to be redirected from said archive specified file destination to said key map specified file destination based upon whether said archive specified file destination matches said key map specified file destination;

wherein upon a determination that said at least one file is to be redirected, generating a modified call back return, said modified call back return including said key map specified file destination; and

sending said modified call back return to said extraction engine, wherein in response to receiving said modified call back return said extraction engine opens a location on a computer system at said key map specified file destination, and

writes said at least one file from said archive directly to said location at said key map specified file destination.

3. The computer implemented method of claim 2 wherein upon a determination that said at least one file is not to be redirected, generating a call back return, said call back return including said archive specified file destination;

and

sending said call back return to said extraction engine, wherein in response to receiving said call back return said extraction engine opens a location on said computer system at said archive specified file destination, and

directly writes said at least one file from said archive to said location at said archive specified file destination.

4. The computer implemented method of claim 2 further comprising:

determining whether there is said at least one file to be extracted from said archive by said extraction engine; and

wherein upon a determination that there is said at least one file to be extracted, said extraction engine generating said call back, and

sending said call back.

5. The computer implemented method of claim 4 wherein upon a determination that there is not said at least one file to be extracted, exiting said computer implemented method.

6. The computer implemented method of claim 2 wherein said at least one file is located in a folder of said archive having a unique key identifier, and further wherein said key map database includes one or more entries, each of said one or more entries associating an archive specified file destination with a key map specified file destination based on at least a unique key identifier.

7. The computer implemented method of claim 1 wherein said extracting said at least one file from an archive directly to one or more final file destinations on a target computer system comprises:

installing a file system hook on a computer system, said file system hook for intercepting and stalling one or more file system events on said computer system;

launching an extraction engine, said launching initiating extraction of said at least one file from an archive by said extraction engine, said extraction engine generating a call to a file system to open a location at an archive specified file destination associated with said file;

receiving a file system event intercepted by said file system hook, said file system event including a file handle identifying said archive specified file destination;

stalling said file system event;

determining whether said file system event is associated with said extraction engine;

wherein upon a determination that said file system event is associated with said extraction engine, determining whether said at least one file is to be redirected from said archive specified file destination to a key map specified file destination;

wherein upon a determination that said at least one file is to be redirected, generating a modified file handle, said modified file handle including said key map specified file destination; and

returning said modified file handle to said extraction engine, wherein in response to receiving said modified file handle said extraction engine opens a location on said computer system at said key map specified file destination, and

writes said at least one file from said archive directly to said location at said key map specified file destination.

8. The computer implemented method of claim 7 wherein upon a determination that said at least one file is not to be redirected, returning said file handle including said archive specified file destination to said extraction engine, wherein in response to receiving said file handle said extraction engine opens a location at said archive specified file destination, and

writes said at least one file from said archive directly to said location at said archive specified file destination.

9. The computer implemented method of claim 7 wherein said determining whether said at least one file is to be redirected from said archive specified file destination to a key map specified file destination comprises:

looking up a key map specified file destination associated with said at least one file in a key map database; and

determining whether said at least one file is to be redirected from said archive specified file destination to said key map specified file destination based upon whether said archive specified file destination matches said key map specified file destination.

10. The computer implemented method of claim 7 wherein said at least one file is located in a folder of said archive having a unique key identifier, and further wherein said key map database includes one or more entries, each of said one or more entries associating an archive specified file destination with a key map specified file destination based on at least a unique key identifier.

11. A computer program product comprising a tangible computer readable storage medium storing computer program code comprising:

an archive stream based install application for directly streaming at least one file from an archive as the archive is being extracted directly to one or more final file locations in a file system, said archive stream based install application comprising;

means for extracting said at least one file from an archive and for writing said at least one file directly to said one or more final file locations in said file system; and

means for redirecting said at least one file from an archive specified file destination to a key map specified file destination; and

means from associating said archive specified file destination with said key map specified file destination.

12. The computer program product of claim 11 further comprising:

an archive, said archive including said at least one file for installation on said computer system.

13. A computer program product comprising a computer-readable medium storing computer program code for a method comprising:

launching an extraction process; and

extracting at least one file from an archive directly to one or more final file destinations on a computer system.

14. The computer program product of claim 13 wherein in said method, said extracting said at least one file from an archive directly to one or more final file destinations on a computer system comprises:

registering a call back with an extraction engine;

launching said extraction engine, said launching causing said extraction engine to obtain an archive specified file destination for said at least one file from said archive, and to generate and send a call back;
