How to open rsd files

What is RSD file:
An RSD file is a type of file format used by computer databases built using structured query language (SQL). RSD files are often encountered when programming databases using computer data management software such as REALbasic.
Instructions:

Step 1:
Open the REALbasic database software program. If you do not own a copy, purchase and download the software at realsoftware.com (see Resources below). REALbasic is available for computers running either the Windows, Mac or Linux operating systems.

Step 2:
Click on "File" in the task bar and select "Open File..." from the menu.

Step 3:
Select your RSD file in the "Open File" dialog box that appears. The REALbasic software will then open the RSD file and extract the appropriate SQL data from the database file.
Step 4:
Save the RSD file after editing it and upload to your online server or a similar backup drive.
Step 5:
Alternatively, you can open a .RSD file by uploading it to your Web server and using a database access program such as phpAdmin to open the file using SQL commands such as "GetFolderItem("filename.rsd")".
