Step 1: Double-click the file.

Locate the SDX file icon and double-click it. If you have the right program installed, it should open the file automatically. If it doesn’t, move on to Step 2.

Step 2: Look for another program.

If the SDX file doesn’t open when you double-click it, you probably don’t have the right program on your computer. There are several popular programs that can be used to open a SDX file. Try one of the three most common programs: Smart Diary Suite Temporary File, CaptiveWorks Satellite Channel Database, or Sample DUMP Exchange File.

Step 3: Check the file type.

If none of the above programs will open your SDX file, check the file type to make sure you have a program that can open that type of file. Most SDX files are Audio Files, but there’s a chance it might be another type.

You can find this information in the file’s properties. On a Windows computer, just right-click the file and click properties, and look for the file type under “Type of File.” On a Mac computer, right-click the file and click “More info,” and look for the file type under “Kind.”

Step 4: Get help from a developer.

If you can’t figure out how to open a SDX file, a developer can probably tell you how. Find the program you have in the table below and contact the developer of that program.

Program Name Developer Name
Smart Diary Suite Temporary File Programming Sunrise
CaptiveWorks Satellite Channel Database CaptiveWorks Inc.
Sample DUMP Exchange File PC Software Company
Midi Sample Dump Standard Files Compacted by SDX Unknown
SatcoDX Channel List Windows Programmer
Quick Sequence Diagram Editor Diagram with Options Markus Strauch

Step 5: Find a universal file viewer.

The easiest way to open a SDX file, or any kind of file, is to use a universal file viewer like File Magic (Download). You can use it to open many different file formats. If it’s not compatible, the file will just open in binary.
