I can open some zip files via the file app that is preinstalled on the chromebook, but some zip files just won't open up for me. I don;t understand why, since all the zip files I downloaded a few days ago still allows me to open them, but the zip files I downloaded yesterday will not open for me. I tried online zip openers, and it said that they didn;t have permission. What is the issues?
