I get a warning "There are some data after the end of the payload data" when extracting an archive. What does this mean? Is the file corrupted?

    Basically, I did a search on this error and 7zip and it was a known issue a few versions back, but it may be related to using the RAR encryption on certain types of data. I haven't done any more research at this point and don't have the time today to do so, but it may be worth googling to see what you find. – music2myear Dec 8 '16 at 1:00

    What is the filetype(s) of the date you're compressing, and what is the approximate uncompressed data size? – music2myear Dec 8 '16 at 16:17
  • @music2myear: ISO, ~ 1,5 GB. Can't share the file sadly. – user598527 Dec 8 '16 at 16:37

    Yea, I don't need the contents, just the file type: ISO. Thanks. – music2myear Dec 8 '16 at 20:03

    With 7Zip 18.06 x64 2018-12-30, and the ISO file hosted by this torrent "Windows_XP_Professional_SP3_x86_-_Black_Edition_2015.9.12", the error is still present. – Brethlosze Jan 1 at 20:25

It appears this is a reoccurring issue w/ 7zip. The most recent note of this that I could find is from build 16.02.

The most recent examples of this are with archives created by other archives (WinRAR, mostly), and I'm sure he'll be interested to hear of your issue with a file that was created in 7zip itself.

I recommend you bring this to Igor's attention over at SourceForge where the 7zip support forums are at: https://sourceforge.net/p/sevenzip/bugs/

Rename the extension from .zip to .rar it will work fine. It may be not done due to compressed in another program and provide the extension as zip.
