A GSP file is a webpage created by Grails, an open source Groovy-based web application framework for the Java platform. It is similar to an .ASP or .JSP file but contains Groovy markup language and tags, which are parsed on a web server that renders the code into HTML and is sent to a user's computer.

Since the Groovy code is parsed on the web server, the end user never sees the GSP code. The end user will only see the HTML generated by the Groovy code in the page. GSP files are used to store templates and layouts for webpages. Templates allow users to create sections of code that can be reused in multiple "views," or webpages, and layouts allow users to create the structure of a webpage, which includes the page title, head tag contents, and body tag contents. All GSP files are located in the grails-app/views directory. NOTE: Grails was previously known as "Groovy on Rails."

File sent by IMail Server, an email server program used by small to medium-sized businesses; contains an error message or flag indicating a problem with the email delivery; typically generated by the mail server postmaster.

GSP files are given in response to the sender of an email when there is an error.

A GSP file is a design created by Silhouette Studio version 3, a program used to design items that can be cut with a Silhouette electronic cutting machine. It contains a design, which may include text, shapes, lines, colors, patterns, gradients, images, and effects. GSP files also store settings for specifying cutting parameters and styles.

The GSP file is similar to the STUDIO and .STUDIO3 files but is specially formatted to be saved directly to an SD card. After saving to the SD card, the card can be placed directly in the Silhouette CAMEO cutter's SD slot reader. This allows designs to be cut by a cutter that is not connected to your computer running Silhouette Studio. To save your design as a GSP file, select File → Save As → Save to Hard Drive.... You can also save your design as a GSP file directly to your SD card bby selecting File → Save As → Save to SD Card.... NOTE: Although the GSP file is created by Silhouette Studio it cannot be opened by the program. It is designed to be used only by the CAMEO cutting tool.
