I've got a file (4GB) which is too big to upload on AWS S3 with unstable internet connection, so I split the file into several parts using WinZip.
So, file.csv
became a series of files:
- file.z01
- file.z02
- ...
- file.z12
After uploading it on AWS S3 I need to unzip it. How do I do it?
You wont be able to do it without the help of an EC2 instance.
If you have already uploaded these small zip files, launch a new EC2 instance, download these files from S3 using curl or wget, combine them together and upload to s3 again.
Since you are using Winzip, consider launching a Windows based instance, as it will be tough for you find a linux based equivalent for winzip.
