What is and what part?

Download Internet files always has been one of the most popular Internet - third place for sending e-mail and surf the web. US Download files software libraries, directories of ftp, YouTube and Google Video, sites, and download MP3 files sent to us as email attachments.

Being so popular activity year, it is mandatory that compresses files to another computer. File compression had combined a number of different files into a single file and can also significantly reduce a very large file to a smaller one. As a result, the transmission of an archive on the Internet is faster and smoother. This article examines a little more compressed files and discusses how to compress and decompress using two of the most popular archiving programs.

Identify compressed files

Most files are compressed in .zip format (if you are using Windows), or (if you are using a Mac) .sit format. The two most popular software programs used to compress and decompress files are WinZip and StuffIt, respectively. There are other programs that do the same, and there are even programs that can compress and decompress files for Windows and Mac system. However since WinZip and StuffIt are the most popular, assumes that you will use either to compress and decompress files.

If you download a file compressed Library Web site or a file that ends with an .exe extension, please note that while the file is compressed, is usually a file to install a program on a computer. ZIP or .Sit queues Don ' t install software - archived simply a collection of them into a single, significantly reducing the size of a large gold.

Decompression of files

Assuming that you have WinZip or StuffIt installed on your computer, you can access that are archived within a file .zip or .sit files by simply double-clicking on the file (a file that ends in an extension .zip or .sit). Then double click on one of these file types will open a window that displays the contents of the file. In most cases, can double-clicking a file within this window to use it, or you can select and drag the file to a folder to view later.

File compression

When you want to upload a file or a collection of files from e-mail to a friend, it is better to archive as a file .zip or .sit first. This will decrease the time it takes to make your computer send it elsewhere, and also decrease the time it takes for someone else to download it.

To create your own .zip or .sit file, you can select a single file or filegroup from within the browser and click the selection. Once again, depending on how you installed WinZip or StuffIt, you can click on the option "Add sit"or"add to ZIP" and have these programs automatically archive the file (s) in one single.

Some files compress better than others, and in some cases, you may not notice much of a difference. Files to compress the best are images, documents and media files. Executable files (files that end with the .exe extension) are compressed not that well, however they are archived by a considerable number of other files, compressed quite well. Go figure!
