List the files inside a ZIP archive, including their sizes, compression details and encryption status, without extracting anything.

Questions people ask
- Does it open or extract my files?
- No. It reads the archive's table of contents (the central directory), which holds each member's name, size and compression settings, and stops there. No member's content is ever unpacked, so the cost is a header read however large or compressed the archive is.
- What does "unsafe names" mean?
- ZIP archives carry their own member path names, and those names can try to point outside the folder they should live in, such as a "../" traversal or an absolute path. This tool flags every member whose name would not survive the safe-path rule (the same rule the extractor enforces), so you can see the problem before you extract anywhere.
- Why does it show two sizes?
- Each compressed member has an on-the-wire size and, when unpacked, a larger size. The report shows both, so you can see how much compression is actually doing and what the archive would take up if fully extracted.
- What about encrypted members?
- The archive's header says which members are encrypted (the flag). Those are counted; the tool does not try to open them. The name, size and method of an encrypted entry are still visible, which is all this tool promises.
- What happens to my file?
- The archive is removed as soon as the job finishes; your report is available for about 10 minutes, then it is automatically deleted with it.
