Searching jpg files and moving using iOS app

WD External Drives My Passport Wireless
1

I want to import sd cards with raw and jpeg files. I then want to search for jpeg files and select them all and move them to another folder.

I can use the wd app to search fro jpegs, but then once they are found I need to select them all to move them. However there is no select all option after doing a search.

Anyone know of a way to do this?
