Java uses ant to implement ZIP files to compress and extract zip files.
A single file is compressed into a zip file, and multiple files are compressed into a zip file.
You can compress large files.
You need to use the Ant.jar file and put it in the Lib directory.

This article describes how to compress and decompress the zip file in Python and try to crack the password of the zip file. It provides a simple example of using the zipfile module, for more information about how to compress and decompress zip files, see python zipfile.
For example, in the directory where The py script is located, there are the following files:
Reason:Java's encoding of text is based on Unicode, so if you use Zipinputstream and Zipoutputstream to handle compression and decompression, and you run into a Chinese filename or path, then of course it's Unicode. However, the current compression and decompression software, such as WinZip, does not support Unicode, and it does not handle a file that is encoded in Unicode with a filename.
So how do you make the compression files that WinZip can handle? There are two ways of doing this:
one is t
Reason:Java encoding of the text is based on Unicode, so if Zipinputstream and Zipoutputstream to deal with the compression and decompression work, encountered in the Chinese file name or path, it is of course the Unicode to deal with ROM. However, now on the market compression and decompression software, such as WinZip, but does not support Unicode, a file name in Unicode-encoded file, it will not be processed.
So how do you make the compression file that WinZip can handle? There are two ways o
