Archiving files is a particularly useful way of storing multiple data files. Many use this process to compress files for portability and to decrease the use of storage space. Businesses, on the other hand, use archive files to prevent data loss and increase security to protect your files from cyber-attacks and data breaches. This is because archive files are not easy to open. Even if your computer has a built-in unarchiver, it cannot open all file formats. With the Unarchiver app, you can open more formats. It is a free file compression application that lets you open any archive files in seconds.
