General Information About ZIP Files

ZIP files are compressed archives that group together one or more files into a single file, compressing the files (making them smaller) that are contained inside. The ZIP file format is very popular for efficiently storing and transferring groups of files in a variety of business and personal applications.

The ZIP file format dates to the late 1980s when it received heavy use in pre-internet-era Bulletin Board Systems, or BBSes. In this era, file transfers occurred using MODEMs and transfer speeds were very limited. Using ZIP compression regularly saved minutes or even hours off of file transfers. It also allowed for multiple files and folders to be grouped together ('zipped') and transferred as a single ZIP file. Once received, the ZIP file would then be opened and its contents decompressed ('unzipped') onto a user's computer.

Today, the ZIP file format remains in heavy use in the internet and in the cloud, with billions of such files in circulation. In the cloud, ZIP files are commonly found as both Gmail attachments, as well as files stored in Google Drive or other cloud-based storage systems such as Dropbox and Microsoft OneDrive.

In addition to compression, ZIP files are archives that can group together multiple files and folders. When this is done, the path and folder information of the file tree is preserved inside the ZIP file. This makes the ZIP file format convenient for sharing and distributing groups of files.

Examples of ZIP File Uses

ZIP files are common across a variety of business areas, including industries ranging from medical, insurance, legal, mortgage, banking and financial, scientific, equities and trading, SEO (Search Engine Optimization), and education industries.

What is the best free zip file opener

Here are some specified real-world examples of actual usage of ZIP files:

  • A car insurance agent ZIPs and emails information related to a person's health insurance, homeowner's insurance, auto insurance, or life insurance policy.
  • A real estate agent scans and ZIPs a sales contract and sends it to a mortgage broker for a home loan when buying a home.
  • An attorney or lawyer for a law firm ZIPs together a set of related legal documents such as a will, trust, claim, or other estate planning documents and shares them with their client.
  • A university student ZIPs a homework assignment and related files and sends it to their instructor or professor in an online degree program.
  • A tax accountant ZIPs and emails a copy of a person's federal and state tax returns for review before filing with the IRS.

ZIP files can contain multiple files of different types. Common files that can be included in a ZIP archive include PDFs, images, videos, and Microsoft Office documents including Microsoft Word, Microsoft Excel, and Microsoft PowerPoint (*.DOCX, *.XLSX, *.PPTX file formats).

Creating and Opening ZIP Files

ZIP Extractor and most modern operating systems have built-in functionality to create ZIP files.

Free Zip File Opener For Windows 7

  • On Windows or PC, to create a ZIP file, right-click files in Windows Explorer and select “Send to -> Compressed (zipped) Folder.”
  • On a Mac running Mac OS, create a ZIP file by right-clicking files in Finder and select 'Compress [name_of_file].”
  • On a Chromebook running Chrome OS, choose one more files in the Files app and then select “Zip selection.”
  • In ZIP Extractor, click 'Create New ZIP' and from there you can add files and folders to be compressed, including files from Google Drive. You can also drag-and-drop files and folders onto the main screen to ZIP them.
  • In your internet browser, you can also use the URL shortcut zip.new to go directly to the ZIP Extractor 'Create New ZIP' screen.

On Windows, Mac, or Chrome OS, a ZIP file can be extracted (decompressed) by double-clicking it. Then, the individual files will be unzipped into a new directory and available to preview, edit, print, etc.

ZIP Extractor provides the same decompression functionality that standard operating systems provide, except that ZIP Extractor supports many more formats than the basic built-in functionality of most ZIP programs. Most importantly, ZIP Extractor is designed bottom-up to work directly in the cloud. Because there is no built-in ability to unzip ZIP files in Google Drive or Gmail, ZIP Extractor is a third-party application that provides this functionality.

Encryption and Password Protection

The ZIP file format provides support for basic password-protected ZIP files. More recently, the ZIP format was enhanced with the ability to create files with strong encryption, using AES (Advanced Encryption Standard). This 'strong encryption' approach is much more secure than the original version, but it is less compatible because Windows and Mac cannot open them. ZIP files using 'strong encryption' require ZIP Extractor, WinZip, or other more advanced program to open.

Other archive formats, including RAR and 7-Zip, also allow passwords. These formats have a special ability to also encrypt the names of the files contained in the archive file (using the supplied password), in addition to file content.
