Abstract

A technique for controlling access to files or directories in a system that includes and overlay involves the use of explicit overlay integration rules. An example of a method according to the technique may include providing an overlay to a file system structure; providing an explicit overlay integration rule; and directing a file access for a file that resides in the file system structure and in the overlay to either the file system structure or the overlay depending upon the explicit overlay integration rule. The overlay may or may not be associated with a streaming software program. The proposed system can offer, among other advantages more control over access to files and directories in the file system/overlay.

Claims

1. A method, comprising:

providing an overlay to a file system structure;

providing an explicit overlay integration rule;

directing a file access for a file that resides in the file system structure and in the overlay to either the file system structure or the overlay depending upon the explicit overlay integration rule.

2. The method of claim 1, wherein the overlay is associated with a streaming software program.

3. The method of claim 1, wherein providing an overlay to the filesystem structure includes:

prompting a user to enter an explicit overlay integration rule;

receiving the explicit overlay integration rule from the user.

4. The method of claim 1, wherein the file in the overlay and the file in the filesystem structure have identical names, but different file details.

5. The method of claim 1, wherein the filesystem structure includes a filesystem directory.

6. The method of claim 1, wherein the filesystem structure includes filesystem files.

7. The method of claim 1, further comprising directing a file access for a file that resides in the filesystem structure to the filesystem structure.

8. The method of claim 1, further comprising directing a file access for a file that resides in the overlay to the overlay.

9. The method of claim 1, wherein the explicit overlay integration rule indicates that a file access for a file that resides in the filesystem structure and in the overlay is to be directed to the overlay.

10. The method of claim 1, wherein the explicit overlay integration rule indicates that a file access for a file that resides in the filesystem structure and in the overlay is to be directed to the filesystem structure.

11. The method of claim 1, wherein the explicit overlay integration rule indicates that a file access for a file that resides in the filesystem structure and in the overlay is to be directed to the filesystem structure or the overlay depending upon characteristics of directories in which the file resides.

12. The method of claim 1, wherein the explicit overlay integration rule indicates that a file access for a file that resides in the filesystem structure and in the overlay is to be directed to the filesystem structure or the overlay depending upon characteristics of the file.

13. A method, comprising:

receiving an access request for a file;

consulting explicit overlay integration rules;

accessing the file in an overlay if an explicit overlay integration rule indicates the overlay has precedence over a file system structure;

accessing the file in the file system structure if the explicit overlay integration rule indicates the file system structure has precedence over the overlay;

accessing the file according to file characteristics if the overlay integration rule indicates the overlay and the file system structure have equivalent precedence.

14. The method of claim 13, wherein the overlay is associated with a streaming software program.

15. The method of claim 13, wherein the file in the overlay and the file in the filesystem structure have identical names, but different file details.

16. The method of claim 13, further comprising providing the explicit overlay integration rule.

17. The method of claim 13, further comprising providing the overlay.

18. The method of claim 13, further comprising determining whether the file is represented in both the overlay and in the filesystem structure.

19. The method of claim 13, further comprising:

determining whether the file is represented only in the overlay or only in the filesystem structure;

accessing the file in the overlay if the file is represented only in the overlay;

accessing the file in the filesystem structure if the file is represented only in the filesystem structure.

20. A system, comprising:

a means for providing an overlay to a file system structure;

a means for providing an explicit overlay integration rule;

means for directing a file access for a file that resides in the file system structure and in the overlay to either the file system structure or the overlay depending upon the explicit overlay integration rule.
