About .R00 files
What a .R00 file is, and what's inside it.
An R00 file is the second volume of a legacy split RAR archive created by WinRAR or compatible tools. You cannot open it alone; you need all parts (.rar, .r00, .r01, and so on) in the same folder, then open the first file (the .rar) with WinRAR, 7-Zip, or The Unarchiver. Split RAR archives can carry malware, so scan extracted contents before running anything.

Do I have to unpack the whole .R00 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 .R00 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.
