File processing is creating, storing, and accessing the content of files. File processing can be used in opening saved files for read-only purposes. It can be used to save a new file or displace the existing one. Through file processing, you can make new files and save the existing files. You can also modify files through this process. Compressing files, folders, and programs decreases their size and reduces the amount of space they use on your volumes or removable storage devices. Volume compression decreases the amount of space that is used by all of the files and folders that are stored on that volume. Because of a potential loss of performance, you may not want to compress some files.
