Recursively take ownership of an entire folder tree and files?

I have a hard drive which someone used to store files for rooting and modding their Android phone. I want to delete that whole folder tree and its contents but it's proving to be stubborn, wanting permission from the user on the other computer.

I have a Take Ownership mod installed in Win 10 x64 and it runs through the whole tree but always fails on a bunch. But if I go to those files and Take Ownership individually it always works. I've taken over and deleted over 8,000 files out of there and am left with not quite 700 to go.

I've tried in Explorer and Agent Ransack to search for *.* to show all the files but the Take Ownership thing is only available in the context menu if 15 or fewer items are selected, but doing that it will only take over 0 to maybe 5 at a time. Dunno why it fails on any of them working recursively when it will work on any of them individually.

Is there a Take Ownership modification that will automatically go to each and every file and folder beneath the top folder its used on, and take ownership of them all?

Got rid of it all. Turns out that good old Unlocker 1.9.2 was able to do the job. Took it a while to plow through everything but got 'er done.
