It is a common practice to compress the contents of a file or folder into a ZIP archive for utilizing the space, keeping backup, carrying data and saving data in more organized and managed way. Moreover, later on extracts that content to a new folder or drive. So for How to Compress and Extract Files, C# ZIP API has made it simple. C# Programmerts can easily integrate API and write code for compression of images, PDF files, Word documents, Excel Spreadsheets even whole folders. API supports ZipCrypto for generating password protected archives as well as using AES encryption to encrypt archive. Even developers can set parallel compression mode or use BZip2, LZMA or PPMd Compression within archive. Below are few sample code snippets for creating C# based zip archives.
