Open RSS file

File extension rss is commonly used for Really Simple Syndication format.

The rss file is stored in an XML (eXtensible Markup Language) format modified to share headlines, annotations, samples of an article etc. through RSS service. RSS means Really Simple Syndication (also known as Rich Site Summary).

The rss XML files can be read in a software called "feed reader" or "RSS aggregator". Popular web browsers, like Internet Explorer, Chrome etc. contain a simple form of RSS aggregator. To subscribe a feed you need to click on an icon in browser that identifies RSS feed of an website.

The initials "RSS" are used to refer to the following formats:

• Really Simple Syndication (RSS 2.0)
• RDF Site Summary (RSS 1.0 and RSS 0.90)
• Rich Site Summary (RSS 0.91)

RSS formats are specified using XML, a generic specification for the creation of data formats.
