What does "There are some data after the end of the payload data" mean?

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?

7-zip

1Basically, 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 – 2016-12-08T01:00:56.133

1What is the filetype(s) of the date you're compressing, and what is the approximate uncompressed data size? – music2myear – 2016-12-08T16:17:37.947

@music2myear: ISO, ~ 1,5 GB. Can't share the file sadly. – user598527 – 2016-12-08T16:37:41.390

1Yea, I don't need the contents, just the file type: ISO. Thanks. – music2myear – 2016-12-08T20:03:27.787

1With 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 – 2019-01-01T20:25:45.217

Same issue with MSDN's en_windows_xp_professional_with_service_pack_3_x86_cd_vl_x14-73974.iso file – Henrique de Sousa – 2019-03-01T11:22:17.677

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.
