Zipinfo (from InfoZIP) will tell you a lot about a file.Sample output from zipinfo -v (using the "verbose" option -v):Archive: /tmp/test.zipThere is no zipfile comment.End-of-central-directory record:------------------------------- Zip archive file size: 22341 (0000000000005745h) Actual end-cent-dir record offset: 22319 (000000000000572Fh) Expected end-cent-dir record offset: 22319 (000000000000572Fh) (based on the length of the central directory and its expected offset) This zipfile constitutes the sole disk of a single-part archive; its central directory contains 1 entry. The central directory is 88 (0000000000000058h) bytes long, and its (expected) offset in bytes from the beginning of the zipfile is 22231 (00000000000056D7h).Central directory entry #1:--------------------------- tmp/bookmarks.html offset of local header from start of archive: 0 (0000000000000000h) bytes file system or operating system of origin: Unix version of encoding software: 3.0 minimum file system compatibility required: MS-DOS, OS/2 or NT FAT minimum software version required to extract: 2.0 compression method: deflated compression sub-type (deflation): normal file security status: not encrypted extended local header: no file last modified on (DOS date/time): 2010 Feb 20 16:22:48 file last modified on (UT extra field modtime): 2010 Feb 20 16:22:47 local file last modified on (UT extra field modtime): 2010 Feb 20 15:22:47 UTC 32-bit CRC value (hex): 3e84c75c compressed size: 22155 bytes uncompressed size: 76774 bytes length of filename: 18 characters length of extra field: 24 bytes length of file comment: 0 characters disk number on which file begins: disk 1 apparent file type: text Unix file attributes (100600 octal): -rw------- MS-DOS file attributes (00 hex): none The central-directory extra field contains: - A subfield with ID 0x5455 (universal time) and 5 data bytes. The local extra field has UTC/GMT modification/access times. - A subfield with ID 0x7875 (Unix UID/GID (any size)) and 11 data bytes: 01 04 e8 03 00 00 04 e8 03 00 00. There is no file comment.If that is not enough, please explain which information you need.Note that zipinfo functionality is actually part of the unzip program (the two binaries are usually identical, or links to each other). You can invoke unzip -Z to get zipinfo's functionality. So if your installation should not have a zipinfo binary, you can use unzip -Z instead.

zipfile: how to set a password for a Zipfile? [duplicate]

A promise on the buffered content of the file.If the file is encrypted you will have to supply a password to decrypt, otherwise you can leave blank.Unlike adm-zip the Open methods will never read the entire zipfile into buffer.The last argument is optional options object where you can specify tailSize (default 80 bytes), i.e. how many bytes should we read at the end of the zipfile to locate the endOfCentralDirectory. This location can be variable depending on zip64 extensible data sector size. Additionally you can supply option crx: true which will check for a crx header and parse the file accordingly by shifting all file offsets by the length of the crx header.Open.file([path], [options])Returns a Promise to the central directory information with methods to extract individual files. start and end options are used to avoid reading the whole file.Example: { directory.files[0] .stream() .pipe(fs.createWriteStream('firstFile')) .on('error',reject) .on('finish',resolve) });}main();">async function main() { const directory = await unzipper.Open.file('path/to/archive.zip'); console.log('directory', directory); return new Promise( (resolve, reject) => { directory.files[0] .stream() .pipe(fs.createWriteStream('firstFile')) .on('error',reject) .on('finish',resolve) });}main();Open.url([requestLibrary], [url | params], [options])This function will return a Promise to the central directory information from a URL point to a zipfile. Range-headers are used to avoid reading the whole file. Unzipper does not ship with a request library so you will have to provide it as the first option.Live Example: (extracts a tiny xml file from the middle of a 500MB zipfile) d.path === 'tl_2015_us_zcta510.shp.iso.xml'); const content = await file.buffer(); console.log(content.toString());}main();">const request = require('request');const unzipper = require('./unzip');async function main() { const

ZipFile utility of zipfile module is a context manager.

With ZIP archives, providing features such as creating, extracting, and managing ZIP files with encryption and compression support:$ pip install pyzipper coloramaNext up, we import the necessary libraries in our newly created file named zip_file_locker.py for instance:# Import the necessary libraries.import pyzipper, argparse, sys, re, getpassfrom colorama import Fore, initinit()We already talked about what pyzipper does. I’m not repeating that :)argparse is a Python library used for parsing command-line arguments and options. We have a tutorial on this library.sys is a Python library that provides access to various runtime system functions and variables. One key one is exiting a program.re is the Python regular expression library for working with regular expressions.colorama is a library that simplifies colored text output in the terminal, enhancing the visual presentation of text with foreground and background colors. We also have a detailed tutorial on Colorama.getpass: is a Python library that lets us enter our passwords without displaying them on the screen. Similar to the way we enter our passwords on the Linux terminal. This is for security purposes.The init() function initializes colorama.This program is CLI-based. Next, we create a function that accepts user arguments from the command line:# Define a function to get CLI commands.def get_cli_arguments(): parser = argparse.ArgumentParser(description="A program to lock a ZIP File.") # Collect user arguments. parser.add_argument('--zipfile', '-z', dest='zip_file', help='Specify the ZIP file to create or update.') parser.add_argument('--addfile', '-a', dest='add_files', nargs='+', help='Specify one or more files to add to the ZIP file(s).') # Parse the collected arguments. args = parser.parse_args() #. The above program extracts a zip file named my_python_files.zip in the same directory as of this python script. The output of above program may look like this: Let us try to understand the above code in pieces: from zipfile import ZipFile.
