How do you make a file undeletable?

[beamrider]

Running W2k Pro, and I need to make several files undeletable. How do I go about this? Do I need to convert the drive to NTFS first and set permissions or something?

you can set the permissions in NTFS....but the owner at least (or administrator) will ALWAYS be able to delete it...or if that is not what you want you can always right click and check the hidden attribute. Then "do not show hidden files"...then you just cant see it...

you should be able to make a file read-only?
