Frequently asked questions
- What is zip bomb protection?
- Zip bomb protection detects maliciously crafted archives that expand to enormous sizes when extracted, preventing resource exhaustion. SnapOtter checks for this before extracting. All processing is local.
- What happens with single-file ZIP archives?
- If the ZIP contains only one file, it is returned directly without being wrapped in a folder. All extraction runs on your self-hosted SnapOtter instance.
- Is it safe to extract unknown ZIP files?
- Yes, the built-in bomb protection guards against malicious archives. Processing happens entirely on your own server, so extracted contents stay within your network.
