The directory *is* a database. Scribble your pointer and have fun finding your file. Even more fun if it points to the middle of some other similar database file.

Yes, exactly. When will you stop pretending that it is a new idea? This is exactly what you want a back up to do. You don't want a back up program to pretend it knows what is not important enough to save. You want a complete record. >>The OS refuses to let >>you back up some of the important stuff.

You can direct all well written Windows programs about where to put their data. There are very few that won't let you. I am not arguing that Windows is less than a dreadful OS. I am suggesting how to make the best of a bad situation. >>When a Microsoft system goes very bad the first thing to try is restoring >>to the previous image.

You can't. Now we are getting to the subject of repair. This is a more complex subject than just making backups. This is why I suggested that the data be on a different disk. This means you know most of what needs to be copied right away. For programs you may be in for a lot of work. On the Windows OS, the installed programs step all over each other. If you have been a good person, you will still have the install disks and know which order they got installed to make a running system.

This is a lot easier to detect than a byte somewhere in the file being wrong. The problem in doing a repair is usually more of a question of finding the defects than correcting them. -- -- kensmith(a)rahul.net forging knowledge
