A GSLIDES file is a presentation created by Google Slides, an online presentation editor included with Google Drive. It contains a URL reference to a Google Slides presentation stored in Google Drive. GSLIDES presentations store text, images, shapes, charts, tables, animations, and video similarly to a .PPTX file.

Google Drive is a cloud-based service that provides file storage and the Docs, Sheets, and Slides programs. Drive can be downloaded and installed in Windows or macOS as a desktop client for synchronizing remote Google Drive files with the local computer. If you install the Google Drive desktop client, your GSLIDES presentations are accessible within a special folder named Google Drive, which is on the local hard drive. This folder is used to synchronize files with the remote Google Drive. The GSLIDES file acts as a pointer to the actual presentation stored online, which means that when you double-click the file the presentation is opened in Google Drive in your default web browser.
The Google Slides interface appears similar to Microsoft PowerPoint with a toolbar that allows you to insert text, images, shapes, tables, charts, animations, images, and Word art. You can also change the background, layout, theme, and transitions in the presentation.
