ZIP files make it easy to group files and make transporting and copying these files faster. These files provide most of the benefits of ZIP files, but use different file formats. ZIP files save time and space, and make downloading software and transferring email attachments faster. It is often useful to send a group of related files to an associate. Rather than distributing individual files it is often easier to distribute the files as an archive to benefit from the file grouping and compression.
Some files are important but used infrequently.
To save disk space simply compress these files into an archive when they are not used, and decompress them only when needed. More Information About Archive Formats ZIP and ARJ files are the most common archive format although ZIP files are the most popular. LZH files are manipulated by the LHA program from Haruyasu Yoshizaki. ARC is an older format. TGZ files are often found on Unix-based Internet sites.
