What is ZIP? What can ZIP do for me?
ZIP files to save storage spaceTo put it simply, ZIP allows you to compress files to save storage space. Zipped files take up much less space on hard drives, flash drives, CDs, DVDs, etc.
ZIP files to speed transmission timeIf you want to quickly send files, ZIP makes the job much easier. By compressing the file(s), sending information via email, FTP, etc. is that much easier – the smaller the file, the faster it will reach its destination.
How does ZIP work?When a file is zipped (compressed), all redundant data is replaced by a smaller reference to that data. This allows the file to be reduced in size for easier storage and/or transfer. When that file is unzipped (decompressed), the reference is replaced by the original data so it can once again be read in its original form.
ZIP is losslessZIP is a “lossless” form of file compression – this means that none of the original data is ever lost.
.ZIP file formatThe ZIP file format is a data compression and archive format. Individual files are compressed to reduce their size and then placed in a ZIP archive. ZIP files are usually labeled with a .zip or .ZIP file extension. ZIP is the most popular file format in the world and is utilized by individual users, businesses, and government agencies to efficiently handle and manage files. The .ZIP Application Note is available here.
