file foliage 

That assortment of files and papers one keeps on the desk at work so that it will not look like there is nothing to do; a protective screen against office busybodies who monitor workloads of other people.

Tim had so much file foliage on his desk that one day in December he suffered a file-slide that swept his full coffee mug to the floor.
