I don't know why that View menu option disappears when your files are displayed in icon mode. I've never seen the "Hide file names" option before now, so this is a recent discovery. I like those.
Does this happen to the same folder? EG, you open one particular folder, and sometimes the 'Hide file names' option is there, but other times it is gone? Or does it happen randomly to all folders?
What I am thinking is, that you have managed to set this up somehow in some folder, but not others, and Vista is 'remembering' the choices.
Have you tried the old "switch" trick? Find a folder where icons are displayed but no file names, (my Vista offers this "Hide file names" for all icon sizes), goto the View icon, (not the menu bar but the bar which has "Organize, Views, Slide Show, Sharing Settings, Burn"), and select details. The names will re-appear in a details listing. Close down Explorer, reboot Vista, and try again.
Another option is to set up a folder as you wish, then go to Tools > Folder options, then the View tab, and click the "Apply to all folders" option. Or you could even try the "Reset Folders" button.
When opening a folder in Explorer menu View "Hide File Names" is somtimes seen and
When not seen, I cannot read the file names in extra large icons and large icons.
When seen, I can uncheck it and extra large icon and large icons file names are seen.
How could include "hide File Names" in the menu in "View"
