Clear files are plastic folders with two sides open to store papers, notes etc. They are usually clear and made of really light plastic.

So far this is the only clear file I have found of Fushigi theres got to be more out there!!

This particular file is huge! Much bigger than the regular files wich measure 8.5" by 12". The file pictured below was sold at the Tokyo International Animation Fair.

This clear file has been scanned by me from my own collection and is not for sale.
