ZIP is the most commonly used archive format today even though there are so many other better formats out there that offers faster compress/extract speed with smaller file size. Windows is probably one of the main contributing factor since the operating system itself is able to extract and compress ZIP files without relying on a third party software. Compressing multiple files into one will most of the time produce a smaller file size which can save web/hard drive space, time, bandwidth and it is also easier to send or download.
As useful as it is, sometimes it can get a bit annoying especially when you only need a few small files from a huge ZIP archive. This would mean you will have to fully download the ZIP file first, then only get to extract the files you want on your computer. An easier way to get around this is to preview the ZIP file and then selectively pick the files you want to download from the archive. Here are 5 ways to do it. 1. Iczelion’s HTTP Zip Downloader
You would be surprised that this open source tool was released in 1998 and yet it still works flawlessly in Windows 7.

All you need to do is run the executable file, enter the direct download link to the URL box and click the Connect button. All files from the ZIP will then be listed at the box for you to download. To download multiple files, press and hold the Ctrl key while using your mouse cursor to select. Finally click the download button and the program will actually create a ZIP file containing only the files you selected.

ArchView is an excellent Firefox addon that allows you to open archive files like a webpage and you can select the files that you want to download.

Just open the direct download links and a new tab will open listing the files found in the archive. You can either Save or Open by right clicking on the files.
