What is a .RSD file?
An .RSD file is a type of data file that is used by the Rosetta Stone program, which is a tool for learning new languages. This file contains important language information that the Rosetta Stone software needs to help you learn. You usually won't need to open or change these files yourself because they are automatically used by the Rosetta Stone program.
These .RSD files are found in special folders named "data" and "speech" inside the Rosetta Stone program files, particularly within a larger file known as an .ISO file on the Language Disc that comes with the software.
The main program that can open and use these .RSD files is Rosetta Stone Language Learning. This means if you're using Rosetta Stone to learn a new language, the program is already designed to access and use the information in these .RSD files without you having to do anything.
For those who are more technically inclined, it's interesting to note that .RSD files are related to RealSQLDatabase files. These could be worked with in a programming environment called REALbasic, which was renamed to Xojo in 2013. Even though REALbasic changed its name, some developers who use Xojo might still work with files ending in .RSD, treating them like SQLite database files, which are another type of database file but usually end with .SQLITE.
In summary, if you're learning a language with Rosetta Stone, the .RSD files are part of what makes it work, but you don't need to worry about opening them yourself. If you're a developer working with Xojo, you might encounter .RSD files as a form of SQLite database.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files. If you want to suggest edits or updates about .RSD file formats, example files, or programs that are compatible. Please contact us.
