Why would you use a ZIP file?
The Zip format is the most popular compression format used in the Windows environment, and WinZip is the most popular compression utility. Zip files compress data and therefore save time and space and make downloading software and transferring e-mail attachments faster.
File compression is a process of "packaging" a file (or files) to use less disk space. Compression software allows you to take many files and compress them into one file, which is smaller than the combined size of the originals.
- In information technology, lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storage, handling, and transmitting content.
- Open that folder, then select File, New, Compressed (zipped) folder.
- Type a name for the compressed folder and press enter.
- To compress files (or make them smaller) simply drag them into this folder.
- It can reduce file sizes by around half. The .zip format uses lossless compression. With this form, the file decompresss to provide an exact duplicate of the compressed file, with the same quality. However, it cannot compress files to a really small size, making it less useful for very large files.
File compression is used to reduce the file size of one or more files. When a file or a group of files is compressed, the resulting "archive" often takes up 50% to 90% less disk space than the original file(s). Common types of file compression include Zip, Gzip, RAR, StuffIt, and 7z compression.
- ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common.
- A compressed file is any file that contains one or more files or directory that is smaller than their original file size. These files make downloading faster easier and allow more data to be stored on a removable media. Common compressed file extensions are .ZIP, .RAR, .ARJ, .TAR.GZ, and .TGZ.
- Zip files make it easy to keep related files together and make transporting, e-mailing, downloading and storing data and software faster and more efficient. The Zip format is the most popular compression format used in the Windows environment, and WinZip is the most popular compression utility.
