ZIP files have been popular for decades. It almost becomes a standard for files compression. Years before, only zip executable was available and we have to do lots of typing under DOS Command Prompt. Then, there came WINZIP and it made life easier for lots of Windows users. Even better, Windows 7 started to natively support ZIP file compression and de-compression.
Today, we are going to tell you how to compress or de-comparess ZIP files on Windows.
I can click on the cab file in question, and the Win10 'Extract' menu is available but every option within it is grayed out. The right click menu will let me 'Send To > Zipped Document', but there's no 'Extract to' option. Google tells me to use Winzip, but I don't have Winzip and I'm not sure I'm allowed to install it on the work PC. It's utterly not OK to move the file to a personal device to extract it. Any other ideas?
That's odd that Windows can't handle it, because cab is a Windows format. Anyway, can you rename the file to .zip? That might convince Windows to try harder. posted by It's Never Lurgi at 2:44 PM on July 26, 2018
7-zip will also work, but you probably don't have that either. Have you double clicked on it? posted by soelo at 2:46 PM on July 26, 2018
If I doubleclick on it, I can get to the files, but there's no internal folder structure, and the other script that needs these files as inputs doesn't accomodate that (and I'm not allowed to edit that script.) posted by janell at 2:53 PM on July 26, 2018
According to Wikipedia, 7-Zip will do it; since it's your work PC, see if you can use 7-Zip Portable. posted by WCityMike at 3:22 PM on July 26, 2018
I use PeaZip portable at work, which also doesn't require an install and is free. http://www.peazip.org/peazip-portable.html posted by matsho at 4:03 PM on July 26, 2018
7zip is a free download and can extract .CAB files. posted by Greg_Ace at 4:33 PM on July 26, 2018
I'm a bit confused. Does your script need to be able to extract the files from the command line, or do you just need to be able to extract the files inside the CAB file yourself? If you can open the CAB file in Explorer to see its contents (which you should be able to on Win10), then you can treat the files inside pretty much like a normal file and copy it to another folder outside of it (either using drag & drop or copy & paste). Alternately, you should be able to use the built-in expand.exe command-line utility to extract the files. posted by Aleyn at 4:34 PM on July 26, 2018

Why would you need cab files if you can't install software on your work PC? I would second 7zip. posted by cjorgensen at 4:59 AM on July 27, 2018
Thanks, all! So after asking around, some of my colleagues have WinZip and others have 7Zip on their work-issued computers, so I must have just gotten a weird build.. and both are available in our internal SW 'store' so I'm golden.
So thanks for pointing me towards the obvious, as well as providing some helpful other strategies. To answer cjorgensen's question: The cab files are generated as the 'configuration backup' and 'audit' documents by/for some specialized equipment. I'm needing to run a particular audit script. The owner of said script, when asked, said they dump the files on yet a third, older, computer to extract them just the way they wrote the script to accommodate and since they have a solution the rest of us just have to find a way to deal. GRAR. Anyway, thanks! posted by janell at 8:58 AM on July 27, 2018
