About .CRX files
What a .CRX file is, and what's inside it.
A CRX file is a Chrome Extension Package, a signed ZIP archive that holds the code and assets for a browser extension. In normal use you never see one because the Chrome Web Store installs extensions automatically. If you have a standalone .crx file, modern Chrome blocks direct installation; rename it to .zip, extract the folder, then load it via chrome://extensions in Developer mode. Only install CRX files from sources you trust.

Do I have to unpack the whole .CRX file?
No. The viewer reads its table of contents first and only unpacks a file when you click it. That works even with multi-gigabyte archives, because we read just the bytes we need.
Can I open password-protected archives?
Yes, for ZIP (ZipCrypto and AES) and 7Z. You'll be asked for the password,. We can't recover forgotten passwords.
Is my .CRX file uploaded anywhere?
No. The code that unpacks the file is downloaded once and then reused.
Why does a .docx or .apk open as an archive?
Because they are ZIP archives under the hood. Office documents, Android apps, Java programs and EPUB books all use ZIP as their container.
What about split archives (.001, .z01, .part1.rar)?
Multi-part archives need all their parts. Today you can open the first part to see the file list; joining parts is on our roadmap.
