SuperUser reader meed96 wants to know how to open a very huge zip file that his Windows system is unable to deal with:
I use an online file backup service (Backblaze) and recently got a new computer. Several files on my old computer were too large to move via my USB drive, so I decided to download them from my backup service.
Specifically, the files included three videos for a total of around 20 GB. However, when I proceeded to unzip them, I got the following error message:
I use a 250 GB SSD and a 1 TB HDD. I failed to pick up a 2.15 Exabyte hard-drive while picking out my new computer though. How do I fix this?
What is the best way for meed96 to get that huge zip file open?
SuperUser contributor Steven has the answer for us:
Use 7-Zip (or another zip utility) to extract the zip file.
- 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.
