To get it to download to the folder you need to right click on each individual block number and then click on "save link as" or "save target as". Not sure how to do it on a tablet or phone. The entire folder contains 114 blocks since I wasn't able to get the first 50 at this time. Its only 42MB so its pretty small. I will get the other blocks at a later date but these will keep me busy for quite a while.
