Re: Copy folders, sub folders and files to another site
Assuming that there are three stages (document library > subfolders > files), try something like that:

First step: Copy library and list its contents (assuming there are only folders in it, otherwise you have to filter, I guess.)

Copy each subfolder of the library and list its contents.

For each subfolders contents, get file contents and create files in recently copied subfolders.
Folder Path and File name are dynamic values from 'Create Folder 2' here.
