Hi there! I managed to find the problem and the solution. First, I've forgot to mention that in my script, oname is an uploaded file. I just inserted a f.close() and voilá! def upload_external(self,file,REQUEST): import os,tarfile ... f=open(oname,"wb") f.write(file.read()) f.close() ... tar = tarfile.open(oname,"r:gz") for itar in tar: tar.extract(itar.name,jobdir) return "Done" Cheers, Alan On 18/07/06, Alan <alanwilter@gmail.com> wrote:

Thanks for your reply.

Yes, my script works and my file are not broken. I am using mac osx tiger 10.4.7, zope 2.9.3 and python 2.4.2.

Cheers, Alan

This is unlikely a Zope issue. Either your tar file is broken or the tarfile module is broken. Check if your code runs without Zope as a simple PythonScript..there is nothing about Zope involved in your issue.
