Answers to Questions (FAQ)

What is a zip comment? (Definition)

A Zip file is used to archive various files by compression. Each file contained in the ZIP archive can be accompanied by a comment (text zone). Also the entire Zip file can contain a global comment.

How to extract the password of a Zip file?

To read the comments of a ZIP archive, it is necessary to list each file and check if it has a comment zone.

The comment can be stored with any encoding (no standard/standard), usually ASCII or Unicode.

Indicate your Zip file click on Read.

How to decode a comment?

The comment can be stored with any encoding (no standard/standard), usually ASCII or Unicode.

Example: The comment 7A 69 70 (hexadecimal format) is encoded in ASCII and translates into the 3 letters: zip

dCode has a cipher detector that can help recognize different encodings.

NB: ZIP files are often encoded (file names, folder names, comments) with code page 437 (CP437) which was widespread before the advent of Unicode and UTF-8.

How does Zip comments reader work?

The tool checks if a global comment exists, and then generates the list of all the files before checking, one after the other, if it contains a comment and tries to decode it.
