PyZipFile is helpful when you need to generate importable ZIP files. Packaging the .pyc file rather than the .py file makes the importing process way more efficient because it skips the compilation step. In this example, you pass 9 to compresslevel to get maximum compression. To provide this argument, you use a keyword argument. You need to do this because compresslevel isn’t the fourth positional argument to the ZipFile initializer. In this example, you use Path.rglob() to recursively traverse the directory tree under root_dir/.
Opening zip file is quite easy in windows 7 but make sure you have a software like winZIP, 7zip or winRAR.

There are rare lossless formats for video since they would take up massive amounts of space. With the development of the Internet, the need for creating better compression schemes and reducing the size of files as much as possible keeps climbing. File compression can be date back to about half a century ago. In the 1970s, computer scientists strived to find ways to reduce the file size and they succeeded—searching through computer code by using mathematical algorithms. A new archive file has now been created, with a .zip extension. It contains all the files that you added but is much smaller in size than their uncompressed total. Here, we’ll uncover how to use 7-Zip to compress and uncompress files.

Only one user is imported as a server administrator; the rest are set to Unlicensed. If you import this file while managing a site, four users are added to that site.
