I don't use my cell phone for down loads or purchases due to the size of screen. Everything is just too small. The other issue may be storage capacity on the phone.
I use a laptop and down load the files as needed to the down load folder. If the file is zipped, do a right click and "extract all". This function makes another folder with the information. That folder is then moved to the correct portable hard drive unit. I have 2 separate ones that almost mirror all files.
