Automated file restore from GHO images created with Ghost 7.5, 7.0 and 6.5

I have a library of ghost files, and it would be useful to get specific information out of them so that they can be inventoried - therefore the process needs to be automated. I know Ghost Explorer has some command line switches (for instance you can get a directory and/or file listing from the command line), but is there a parameter to restore a single file or directory? If that is not possible, is there any Symantec product I can use to “update” the images and perform the same task?
