More likely (if they are on AIX) that they are using info-zip
(https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Finfozip.sourceforge.net%2F&data=02%7C01%7CPColeman%40us.imshealth.com%7Cd16ad0a36cee47176ea808d6225a5f10%7C5989ece0f90e40bf9c791a7beccdb861%7C1%7C0%7C636734168884438637&sdata=P4QZzCtbi3lIOceD1WOynvbkeTTB37rtvVL3%2BHi32yQ%3D&reserved=0)
which is at version 3.0.
On most gnu/linux system, you should have the "file" utility installed, which
can be used to detect the file type.
Examples:
=====
$ file unknown1.bin
unknown1.bin: Zip archive data, at least v2.0 to extract
$ file unknown2.bin
unknown2.bin: gzip compressed data, last modified: Mon Sep 24 13:26:32 2018,
from Unix =====

A good way is to ask the sender to calculate the checksum of their file before
uploading it.
Then you can calculate the checksum of the downloaded file.
If they are not exactly the same - you have some corruption.
On AIX, they should run:
$ shasum archive.bin
f572d396fae9206628714fb2ce00f72e94f2258f archive.bin
After you download the file, check again:
$ sha1sum archive.bin
f572d396fae9206628714fb2ce00f72e94f2258f archive.bin
(Note the program name is "shasum" on AIX and "sha1sum" on gnu/linux).
hope this helps,
