The RB file extension is related to Rosebud, a German Windows phone app. Rosebud allows controlling devices via SMS. The RB file is a configuration file for Rosebud. The RB format description is an application/octet-stream MIME-type. It is a Rosebud profile file. The RB file may be misspelled or accidentally changed. This can make it unrecognizable. The file extension may be incorrectly specified.

We provide information on software, editing instructions and conversions for RB files. Our aim is simplifying the process of using the .rb file format. Many share .rb files without instructions. This makes determining compatible editing programs difficult. We offer guidance on handling .rb files for effective use.

The RB file extension has 6 associated file types in our database. These include Rocket eBook, RealBasic Source Code, Ruby Console Application, Rosebud Profile, SketchUp Plugin Script and Divinity: Original Sin RB Data. Problems with .rb files can often be fixed by updating the application used to open them. Scanning for viruses may also help. The .rb file extension is primarily associated with Divinity: Original Sin, a game files application by Larian Studios.
