Zip files contain one or more files. Zip files make it easy to group files and make transporting and copying these files faster. Zip files save time and space, and make downloading software and transferring e-mail 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. A good program for this is WIN Zip . This makes the download faster, and insures that all your information is included. Keep in mind that all the so called free sites on the Internet are able to give you actual free space because they sell advertising, on your site, to various business. These ads pay for upkeep and administration of the web site.
