Many times we require only selected files from an archive but had to download the full archive because there is no other option, free windows application LoadScout is an easy solution to this problem but if you are uncomfortable installing a standalone application for this rarely used functionality, Firefox addon ArchView will get the job done right from your browser.

Once installed Archview lets your preview RAR, ZIP and ISO files online without downloading the whole archive.

The open-source project is hosted at Sourceforge - http://archview.sourceforge.net/, and the Firefox addon can be downloaded from official page here.
