and dest2 was me trying different ways to write to the sever, unc or
mounted drive. that's for later :P
i missed this "as missing parent directories."
shutil.copytree(src, dst[, symlinks=False[, ignore=None]])¶
Recursively copy an entire directory tree rooted at src. The
destination directory, named by dst, must not already exist; it will
be created as well as missing parent directories.
so for testing i did the copy once. deleted the files in top folder,
and deleted a folder deeper in.
gave error when tried to copytree the deeper in folder.
is there something like mkdir?
