Cant move files from int sd to ext sd, on android 5

[Android Central Question]

Have tried several file mngrs : es, total cmndr, b1, CX, etc all come back with same thing about root permissions in android for ext SD card.
I'm all at sea on that, don't understand.
Is there an app that can do this?
I'm on a brand new Chuwi hi10 pro.

Many file managers will tell you how to choose the SD card as the destination - you have to follow that.

Otherwise, create a folder on the card and you should be able to copy things to it. (Don't Move - if a Move blows at the wrong time you could lose the file. Copy - then if it works, delete the original.)
