shutil.move() does not preserve file and directory
ownership when moving a whole directory tree to a
different filesystem. This does not happen when
shutil.move() is used to move a directory tree within
the same filesystem.
Version: python 2.4.2

I have had a look at the source code in and
noticed that shutil.copystat() does not copy the
ownership information, whereas "stat" command does
output information about the ownership (on GNU/Linux at
The only discussion I found refering to file /
directory ownership and possible security implications
(if any) can be found here:

While this is surprising, this is documented behavior:

"If the destination is on the current filesystem, then simply use
rename. Otherwise, copy src (with copy2()) to the dst and then remove src."

And copy2() uses copystat() and does not copy "contents, owner, and group".

That's because there's no simple, portable way to copy all metadata.

If you need to copy all of them you will need to use OS-specific APIs
