All files in my computer seem to have read only permission. I am unchecking
the read only property in general tab in Properties of Folder pressing Apply
or Ok button but after I again attempt to see the Folder Properties but
again it seem to have read only property. Changes never be applied.

I need write access property when connecting an access database but because
of this problem it is not permitted

Pelease Help!
