Does Google read your files?

Google said that it does not technically read files, but instead uses an automated system of pattern matching to scan for indicators of abuse. Though it can identify clusters of data that might suggest a violation, the system does not pull meaning from the content, according to a company spokesperson.

How are password protected ZIP files still secure?

Encryption is done on the files not the container itself, so confidentiality & integrity are still granted for the files inside. The ZIP archive itself isn’t password-protected, but the files inside are.
