Abstract

A method in a computer system enables the translation and opening of a document which was created by an application program no longer resident in the computer system. The method begins by identifying the file format of the target document, Subsequently, all computer resident applications capable of opening the document are identified and translation paths from the document to the accessible application programs are calculated. Each of the available application programs and corresponding translation paths are listed in order of fidelity, with an indicia identifying the preferred path. One of the translation paths is selected and the document is translated into the acceptable format. Following translation of the program, the application is launched and the newly translated document is opened.

Claims

1. A method in a computer system for processing a document created previously by an application program which is not currently accessible by the computer system, comprising the steps of:

determining that the application program that created the document is not accessible by the computer system;

identifying application programs that are accessible by the computer system that are different from the application program that created the document and are capable of translating the document;

calculating translation paths from the document to the accessible application programs;

selecting one of the accessible application programs capable of translating the document; and

using the selected application program to translate the document into a format acceptable to an accessible application program.

2. The method according to claim 1, wherein following the step of using the selected program to translate the document, the method further comprises the step of launching the accessible application program.

3. The method according to claim 2, further comprising the step of opening the document.

4. The method according to claim 1, wherein following the step of identifying programs, the method further comprises the step of listing the accessible programs in order of fidelity.

5. The method according to claim 4, wherein the listing of programs includes an indicia indicating the preferred choice from among the programs based on fidelity.

6. The method according to claim 4, wherein the listing of programs includes an identification of translation paths.

7. The method according to claim 1, further comprising the step of identifying the file format of the document.

8. The method of claim 1 wherein the computer system is connected to a communications link, and further comprising the step of:

searching via the communications link for remotely located programs that are capable of translating the selected document.

9. The method of claim 1, further comprising the step of determining that a currently operating application program is incapable of translating the document.

10. An apparatus for processing a document created previously by an application program which is not accessible by a computer system, comprising:

means for determining that the application program that created the document is not accessible to the computer system;

means for identifying application programs that are accessible by the computer system that are different from the application program that created the document and are capable of translating the document;

means for calculating translation paths from the document to the accessible application programs;

means for selecting one of the accessible application programs capable of translating the document; and

means for using the selected application program to translate the document into a format acceptable to an accessible application program.

11. The apparatus according to claim 10, further comprising means for launching the accessible application program.

12. The apparatus according to claim 10, further comprising means for identifying the file format of the document.

13. The apparatus according to claim 10, further comprising means for opening the document.

14. The apparatus according to claim 10, further comprising means for listing the programs in order of fidelity.

15. The apparatus of claim 10 wherein the computer system is connected to a communications link, and further comprising:

means for searching via the communications link for remotely located programs that are capable of translating the selected document.

16. A computer usable information storage medium storing computer readable program code means for causing a computer to perform the steps of:

displaying a list of document files for selection by a user of the computer;

detecting a user'"'"'s selection eta listed document file;

determining that the application program that created the selected document file is not accessible by the computer system;

identifying application programs accessible by the computer system that are different from the application program that created the document and are capable of translating the document file;

calculating translation paths from the document to the accessible application programs;

selecting one of the accessible application programs capable of translating the document file; and

using the selected program to translate the document file into a format acceptable to an accessible application program.

17. A method for computer system processing of a document file created previously, comprising the steps of:

using the computer to display a list of document files;

selecting a document file;

determining whether the application program that created the document file is currently accessible by the computer system, and if not then

identifying application programs accessible by the computer system that are different from the application program that created the document and which are capable of translating the document file;

calculating translation paths from the document to the accessible application programs;

selecting from the identified application programs a application program capable of translating the document file; and

using the selected application program to translate file document file.

18. The method of claim 17 further comprising after the step of translating the document file, the step of using the selected program to open the document file.

19. The method of claim 17 wherein the step of identifying programs comprises the step of listing the identified programs in order of fidelity of translation.

20. An apparatus for processing a document file created previously, comprising:

computer system memos for listing document files;

means for selecting a document file listed by the computer system means;

means for determining that the application program that created the document file is not accessible by the computer system means;

means for identifying application programs accessible by the computer system means that are different from the application program that created the document and that are capable of translating the document file;

means for calculating translation paths from the document to the accessible application programs;

means for selecting one of the identified application programs; and

means for using the selected application program to translate the document file.

21. A computer usable information storage medium storing computer readable program code means for causing a computer to perform the steps of:

displaying a list of document flies for selection by a user of the computer;

detecting a user is selection of a listed document file;

determining that the application program that created the selected document file is not accessible by the computer;

identifying application programs accessible by the computer that are different from the application program that created the document and that are capable of translating the document file;

calculating translation paths from the document to the accessible application programs; and

using the selected application program to translate the document file.
