Im overtired and blunt so Im trying (real hard) to be polite.
1./ if you mean the icon in the menu BAR, right click and select "customize"
and highlight the folder options icon, "add" .
2./If you mean the menu on the left side of the window (ie:file and folder
tasks, details etc.) then you must drag your window size to become 'wider'.
3. If you mean from the actual menu (file, edit, view..) then you made a
mess only a diapered child could make and must stew in your own crapulance.
Or maybe navigate to Tools > Folder Options.
What folder do you wish to unhide? WTF do you mean anyway, If you know the
name of the folder you can type it into the address bar of any (MS) Window
(C:\documents and settings\"my hidden folder", then right click > properties
'clear hidden box' > press OK.
If I forgot some detail please don't hesitate to let me know.
I used to think girls were complicated.
