What are Compressed Files? Definition and list of extensions

Compressed file extensions: Compressed files use file compression in order to save disk space. File compression is used to reduce the file size of one or more files. Compressed file formats can also compress a group of files. When a file or group of files is compressed, the resulting “file” is reduced by 50% to 90. This process removes redundant data in each file by replacing common patterns with smaller variables. For example, words in a text document can be replaced by numbers or other identifiers. These identifiers refer to the original words that are stored in a key within the compressed file.

Compressed file extensions: Compressed files are widely used on the Internet. Like other files, compressed files contain data that is stored by one or more files in reduced form.

Compressed file extensions: While file compression works fine with text files, binary files can also be compressed. By locating repeated binary patterns, a compression algorithm can significantly reduce the size of binary files, such as applications and disk images. However, once a file is compressed, it must be uncompressed in order to be used. If you download or receive a zipped file, you will need to use a file unzip program, such as WinZip or StuffIt Expander, to unzip the file before you can view the original content.

Common compressed file extensions include .ZIP, .SITX, .7z, RAR, and .GZ.
