Windows File is ludicrously huge and I cannot unzip it

Use a different file archive tool (such as 7-Zip) to unzip the files.

Not all .ZIP features are supported by the Windows Compressed Folders capability. For example, AES Encryption, split or spanned archives, and Unicode entry encoding are not known to be readable or writable by the Compressed Folders feature in Windows versions earlier than Windows 8.
