To improve security, we will soon start forcing password resets for any account that uses a weak password on the next login. If you have a weak password or a defunct email, please update it now to prevent future disruption.
I've used both zip file extraction programs before and am quite content with them as well. 7Zip is a good choice as well, but I have found it to be a bit heavy on processing (i.e., a resource hog) at times when using the application. But this is unique to a person's computing specs as well. So, it might not be an encounterable problem on your end when using 7Zip.
