Question How to access internal data from a previous rom.

Recently installed Dirty Unicorns 4.4.2. Flashed from Macks ALLSTAR. I have es explorer and Drives application the internal data dose not show with theses app. If I boot in to recovery I can see all of my internal data. How can i gain acess to my files. DU ROM is based off of omni using cyanogen tree, I have never flashed rather of those is it common to loose access to that internal memory?
