I will never buy a file folder without checking the surface with my fingers again...check for the degree of smoothness and tooth...you would be well advised to do the same if you want to avoid heartache and misery!
(Sorry, that was a little over the top but I was "forced" to listen to a nano second of the better half's prefered music just then, as I was copying a disc...it affects me rather badly!)
Bye now,
Di
