i tried to place the block as told, source uri remain same which i initially entered
still not working?
here tree uri is
content://com.android.externalstorage.documents/tree/primary%3AAndroid%2Fmedia%2Fcom.whatsapp%2FWhatsApp%2FMedia%2FWhatsApp%20Documents
here target parent uri is
content://com.android.externalstorage.documents/tree/primary%3AAndroid%2Fdata%2Fio.makeroid.companion%2Ffiles
Do you have write access to this?
However your blocks are still wrong. I’ll post the blocks as soon as possible.

yes read and write access are given to the whatsapp document folder
Unfortunately, it is not possible currently to copy files from /Android/media folder with SAF, but you can expect something from v1.1 .
However you can copy files manually also, by reading and writing its content.
Also you can use file manager extensions to copy files. @bodymindpower

Of course its possible. You can use your FileTools or the TaifunFile extension or the File component for that (and of course you need READ permission for this).

Have a look here:
So now you just need to get byte array from the file and write it wherever you have access.
I said you can copy file from /Android/media/, but there might be some special sub-folders like yours /storage/emulated/0/Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Documents/ that only certain apps (like WhatsApp) can access.
I created the subfolder /whatsapp manually, because (as I said) I never used Whatsapp (and will NEVER do).
Try this, it will work for sure

I tried it on a device of one of my children (who sadly uses WhatsApp 
) and it is true that it is not possible to access these (specific) WhatsApp folders (files in these folders). Obviously, this is only possible for the WhatsApp app.

Seems doubtful but worthy a try.
With SAF it is possible.

Yeah right, it should work with SAF.
I’ll check it out quickly.

Tested on Android 10.
