Copy files into one directory, ignoring the directory level

[warem]

How can I copy all files in specific directory to another directory, ignoring the directory levels? For example, in the source directory, it is

--root
--dir1(has many files)
--dir2(has many files)
--dir3(has many files)
.
.
.

then in target directory, all the files are copied/moved in root without the directory levels. The directory levels in source directory could be very deep.

Branch View in Source
Other side into the target dir
Ctrl-A to select all files in source
Copy (don't select "Keep relative path..." in the copy options)

@Horst.Epp: it works. Thank you.
