How to adjust column width in File Explorer?

Tech-Archive recommends: Speed Up your PC by fixing your registry

There seems to be no feature to let you adjust the width of the
filename/date/size columns in File Explorer, as you can in Win
Explorer.

On my iPAQ, it only takes about 14 chars. to make a filename too long
for full display, invoking terminating ellipsis.

Another WM5 no-show?
