However!... (!!). I am able to extract the file with standard tools on Linux (Nautilus and archiver GUI), and with WinRAR 6.21 (64-bit) on Windows. Using the same exact password as with 7-Zip, PeaZip, et.al. I have reason to believe that there is something inherently wrong with the Zip file because it was created on a Mac computer. The file was mailed to me on a USB flash drive. On a brand new SanDisk flash drive. By a member of a privacy team, at a company that I previously worked for. I have no reason to believe that the file is corrupted. How could it be? If it works on Linux? And even on Windows with the help of WinRAR?
