What is Encore in My Files and can I delete it?

[cathyt13]

I am new to the android family, having converted from the Iphone 5 to the S4 a couple of months ago. I have been trying to figure out what is taking so much space on my phone and it is a folder called Encore in the My Files area. What is this for? It has thumbnails of texts, emails, photos etc. I deleted over 15,000 items in the folder two days ago and it is already back up over 2500. How can I stop this and where did it come from? I can't have all my storage used up every few days! Can I delete the entire folder?

Seems to be a file that stores a copy of each multimedia text message you receive. I disabled the att messages app and delete the en core file so far its working ok
