Image Conversion Error

[Han]

Hello, Thanks for the nice program!

My images are in
CollectionDirectory = 'D:\DDSM\Benign';
and I want to save it to below location
pathToJPEGandDDSM2RAWfiles = 'D://DDSM2//Benign//'; here

when I run Matlab codes,

I faced error messages like below.
Can you help me out?

My Matlab version: R2015b
OS: Window10

Warning: Directory already exists.
