The problem is not that warnings are shown, as I agree that they should be, instead it's that 7-Zip needlessly produces corrupt 0-byte files when instead if should correctly unzip the data that is actually there, like all other major zip utilities do, in addition to warning about the possibility of corruption. Then the user can decide after opening the file whether it seems valid or not. There is no benefit to 7-Zip needlessly replacing often valid and not corrupted files with 0 byte placeholder...

For reference, those .zip's were created via "Send to > Compressed (zipped) folder" with Windows 7 Pro SP1, from the developer who produced them, as opposed to my Windows 10 Pro x64 PC used for testing unzipping them.
