Andrei Kulakov added the comment: Liu: Thanks for the report! By the way on re-reading my message, of course by opening and closing archive on each file using the `with` block, you take care of the first issue I mentioned (although it's not very efficient). And I assume there was no multipr

Andrei Kulakov added the comment: Liu: apologies for the confusion, I missed that when coming back to the thread for the 2nd time. I took a look at the code and one potential issue I see is that you are opening the file in 'w' mode if stat size is 0 (or if file isn't valid), and in 'a' mode

[issue41102] ZipFile.namelist() does not match the actual files in .zip file

Serhiy Storchaka added the comment: It is not a bug in archivers, it is just a broken archive. The ZIP archive contains a central directory which lists all files in the archive, so the archiver can just read the central directory without reading all archive to get the list of files. There ar

Xiaolong Liu added the comment: Andrei: The zipped file was created by zipfile module of Python. That's the reason I posted it here. I achived more than 2000 files to the abnormal zipped file. And no tool can extract whole files archived within. 7zip got the first part, and other tools g

Andrei Kulakov added the comment: Liu: Thanks! Google zip also shows 674 files in this archive, so it appears that it's not a Python-only issue. Can you test it with a few zip programs, ideally on a 2 or more platforms, and check which of them report more than 674 files? (I simply opened th
