Very well then. I did search google, and found a number of python scripts that already do the job (more or less). But when I try to tweak them to my specifications, I get errors ... probably because I don't really understand how the process of uploading a file via a webform to a cgi works. For e.g, take the script at this url. http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/273844 By reading through this script, I know that simply putting '<input name="file_1" type="file">' in your web form will establish a connection to the cgi when the client submits the form. The python interpreter obviously sustains that connection while the file is being transferred, the file being part of the FieldStorage() instance. But then, the script saves the file to the disk in some special way I don't understand. In this case: > fout = file (os.path.join(upload_dir, fileitem.filename), 'wb') while > 1: > chunk = fileitem.file.read(100000) > if not chunk: break > fout.write (chunk) > fout.close() chunk = fileitem.file.read(100000), and fout.write (chunk) seem to be the key statements. Could someone elaborate on these for me please? And why do they need to be in a while loop? -- http://mail.python.org/mailman/listinfo/python-list
