I organise my holidays in folders. Each holiday has sub folders for flights\hotels etc. Once the holiday is done I want to move the whole folder to "Past Trips". I used to be able to do this but no longer can.

Here's what I have to do.
Create a new folder in past trips with a dummy name.
Move each subfolder in the current trip to the new dummy folder.
Move any mails in the main current trip folder to the new dummy folder.
Delete the original folder.
Rename the dummy folder the the name of the trip.

I used to be able to do this in one step.
