Step 1: Double-click the file.

Locate the STM 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 STM 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 STM file. Try one of the three most common programs: Sound File, Medlin Accounting Statement Layout, or SDR99 Speech Recognition Task Time Segment Time Marked File.

Step 3: Check the file type.

If none of the above programs will open your STM file, check the file type to make sure you have a program that can open that type of file. Most STM files are Data 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 STM 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
Sound File Windows Programmer
Medlin Accounting Statement Layout Medlin Accounting
SDR99 Speech Recognition Task Time Segment Time Marked File Windows Programmer
Exchange Server Streaming Store Microsoft Corporation
Scream Tracker v2 Module Microsoft Developer
Prosa State Transition Diagram Model Insoft Oy
PhotoStudio Stamp ArcSoft Inc.
Sealed HTML Document SealedMedia
LloydsTSB Bank Statement LloydsTSB
SHTML File Microsoft Developer

Step 5: Find a universal file viewer.

The easiest way to open a STM 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.
