About .PUP files
What a .PUP file is, and what's inside it.
A PUP file is a Sony PlayStation firmware update package (PS3UPDAT.PUP, PS4UPDATE.PUP, PS5UPDATE.PUP). You do not open it on a PC. Copy it to a FAT32 USB drive in the exact folder Sony specifies, then install from the console's System Update menu. The file is digitally signed and encrypted, so it cannot be edited or converted.

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