This means they are in a special compressed format that your Mac must decompress before you can do anything with the contents. This kind of compression serves two purposes. First, it reduces the overall size of the files in order to transfer them faster by email or over the web, and to make them more space efficient on a hard drive or other media. Second, this method allows you to bundle any number of separate files into a single archive, again, making them much more convenient to transfer over the internet..<!--more--><\/p>\n<div id=\"toc_container\" class=\"no_bullets\"><p class=\"toc_title\">Contents<\/p><ul class=\"toc_list\"><li><a href=\"#Compressed_Files\"><span class=\"toc_number toc_depth_1\">1<\/span> Compressed Files<\/a><ul><li><a href=\"#Opening_Compressed_Formats\"><span class=\"toc_number toc_depth_2\">1.1<\/span> Opening Compressed Formats<\/a><\/li><li><a href=\"#Creating_Compressed_Files\"><span class=\"toc_number toc_depth_2\">1.2<\/span> Creating Compressed Files<\/a><\/li><li><a href=\"#Images_Music_Video_Compression\"><span class=\"toc_number toc_depth_2\">1.3<\/span> Images, Music &amp; Video Compression<\/a><\/li><li><a href=\"#StuffIt_vs_ZIP\"><span class=\"toc_number toc_depth_2\">1.4<\/span> StuffIt vs ZIP<\/a><\/li><li><a href=\"#How_Lossless_Compression_Works\"><span class=\"toc_number toc_depth_2\">1.5<\/span> How Lossless Compression Works<\/a><\/li><\/ul><\/li><li><a href=\"#Links\"><span class=\"toc_number toc_depth_1\">2<\/span> Links<\/a><\/li><\/ul><\/div>\n<h2 style=\"text-align: center\"><span id=\"Compressed_Files\"><span style=\"font-size: 18pt\"><strong style=\"font-size: 18pt;text-align: center\">Compressed Files<\/strong><\/span><\/span><\/h2>\n<h3 style=\"text-align: center\"><span id=\"Opening_Compressed_Formats\"><span style=\"font-size: 18pt\"><strong>Opening Compressed Formats<\/strong><\/span><\/span><\/h3>\n<p style=\"text-align: justify\">There are many different compressed file formats. Your Mac can open most of these types of files without using any extra software. Double-click the file, and a new unzipped version will appear next to the original. However, at some point you may be sent a <em>StuffIt<\/em> file, in which case you\u2019ll need a free application called <em>StuffIt Expander<\/em> to open it.<\/p>\n<h3 style=\"text-align: center\"><span id=\"Creating_Compressed_Files\"><span style=\"font-size: 18pt\"><strong>Creating Compressed Files<\/strong><\/span><\/span><\/h3>\n<p style=\"text-align: justify\">If you\u2019re sending files by email, or trying to save disk space, the easiest way to compress them is to make a ZIP file. To do so, select one or more files and folders, right-click, then choose <em>Compress<\/em> from the context menu.<\/p>\n<h3 style=\"text-align: center\"><span id=\"Images_Music_Video_Compression\"><span style=\"font-size: 18pt\"><strong>Images, Music &amp; Video Compression<\/strong><\/span><\/span><\/h3>\n<p style=\"text-align: justify\">The type of file compression we just discussed is known as lossless compression, meaning that the data that comes out when the file is unzipped or unstuffed will be identical to what you put in. This action is distinct from the lossy compression widely used for shrinking sound, image, and video files.<\/p>\n<p style=\"text-align: justify\">With lossy compression, the computer applies ingenious methods of picking out which bits of data we notice least, and discards them. Unlike lossless compression, this is a one-way process. You can\u2019t take a compressed music or image file and turn it back into the uncompressed original. Sound, video, and image files can withstand degradation through file compression, but you could never perform the same techniques on a text or a number document. Words and numbers are types of code, so a minor change can completely alter their meaning..<\/p>\n<h3 style=\"text-align: center\"><span id=\"StuffIt_vs_ZIP\"><span style=\"font-size: 18pt\"><strong>StuffIt vs ZIP<\/strong><\/span><\/span><\/h3>\n<p style=\"text-align: justify\"><em>StuffIt<\/em> was once the most widely used compression format on Macs. <em>StuffIt Expander<\/em> was included in OS X up to version 10.3. Compared with ZIP files, <em>StuffIt<\/em> archives are better at squashing data to the smallest possible size. However, OS X can now handle many compressed formats itself.<\/p>\n<h3 style=\"text-align: center\"><span id=\"How_Lossless_Compression_Works\"><span style=\"font-size: 18pt\"><strong>How Lossless Compression Works<\/strong><\/span><\/span><\/h3>\n<p style=\"text-align: justify\">When a file is zipped up or stuffed, the computer looks for repeating patterns that it can represent more concisely. For example, if you save a document containing the text, \u201csell now, sell used electronics, sell Apple products, sell used Apple computers,\u201d the compression program would notice that the word \u201csell\u201d occurs more than once. It would then assign each of these collections of letters a more concise symbol. In reality, of course, the situation is much more complex. The computer would use numbers rather than symbols, but the basic principle is the same.<\/p>\n<h2 style=\"text-align: center\"><span id=\"Links\"><span style=\"font-size: 18pt\"><strong>Links<\/strong><\/span><\/span><\/h2>\n<ul>\n<li style=\"text-align: justify\">Have you checked out our prices recently?
