Why has the order of files changed in My Documents?

[Bel10]

Although still in alphabetical order, my files and folders are now sorted
'backwards' - i.e. they are sorted from the end of the alphabet to the
beginning. This is really annoying because all my folders are now at the end
and I have to scroll right through to the end to access them. I have
obviously done something accidentally which is really simple but am too
ignorant to know what!! Anyone help me to put it back, please? Thanks

Double click on the header line to reverse the order.

A single click is all that's required, but you must be in Details view to
use it.
