There's several problems embeded here:
1) How do you tell that the files are the same?
a) Filename? - What if you changed the contents but not the name?
b) Filesize? - Which one is newer?
c) Date/Time Stamp - Some transfer methods do not update the
date/time stamp.
2) How do you plan on transfering the files?
a) Http?
b) FTP?
c) Snailmail?
d) SMB Mount?
e) NFS Mount?
3) Are these out of a single directory? Or a directory tree?
To point you part of the way, check the python demos for
FTPMIRROR.
If you are going to be doing this via FTP then FTP mirror does take
date/time stamp into account. (That's assuming I'm remembering correctly.)

Subject: How to solve a problem?
Hi,
My program downloads regularly some files and it takes some
time so I need to shorten this downloading time. As most of these
files are the same, many times when the program downloads these
files, I would like to download only those that are not the same or
are newer. What is the best solution?
Many thanks for help.
Ladislav
