Take a look at the things in shutil (especially shutil.copy and
shutil.copyfile) and os (especially os.rename and os.renames).

I'd like to point out that especially if the files are indeed huge, then
the operating system file copy operations may be *much* more efficient
than shutil.copy*, e.g. by using mmap when appropriate.

os.system() can be your friend...

Matthias,

You'll have to open the input and output file, then read and write chunks
yourself, for example (untested!):

def copy(fromfile, tofile, chunksize=8192):
f = open(fromfile, "rb")
t = open(tofile, "wb")
data = f.read(chunksize)
while data:
t.write(data)
data = f.read(chunksize)
f.close()
t.close()

shutil.py in lib/.

Look at the shutil (shell utilities) module, it has a copyfile function.
Moving a file (within the same file system) is accomplished by os.rename.
To move a file across filesystems you must use copy, then os.remove the
original.

Thanx a lot for all the answers.
I have used the shutil.py and it works fine. May a bit slow baut for
now its fast enough !
