Opening MS9 Files

The MS9 file type is primarily associated with Multisim.

MS9	File extension: MS9
	File type:	Design

What is an MS9 file?

MS9 files mostly belong to Multisim by National Instruments Corporation. The NI Electronics Workbench Group (formerly Electronics Workbench) equips the PCB designer with tools for schematic capture, interactive circuit simulation with SPICE, board layout with autorouting options, and integrated prototyping and test.

How to open an MS9 file

You need a suitable software like Multisim to open an MS9 file. You need a suitable software like Multisim from National Instruments Corporation to open an MS9 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MS9 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MS9 file directly in the browser:. Just drag the file onto this browser window and drop it.

What to Do When a .MS9 File Fails to Open

A .MS9 file can originate from different programs and isn't universally openable.

1. Identify the Source: If it came from an electronics engineer or a circuit design workflow, it is likely a National Instruments Multisim 9 schematic.
2. Check the Header: Open the file in a hex viewer or text editor to inspect the first bytes:
   • "PK" indicates a zipped archive.
   • Readable XML or plain text suggests structured data.
   • Binary gibberish usually implies a proprietary compiled format.
3. Use the Original Software: The original program is usually required; try National Instruments Multisim, or ask the sender if you are uncertain.
4. Use this Webpage: Drag and drop the file into our viewer to detect the format, extract readable text/metadata, and preview when possible.

MS9 file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. In the following you will find our evaluation of the MS9 files:

MS9 is seldom used as a file extension and is primarily used by a single program. The file formats most commonly found in MS9 files are:

• 98% of all MS9 files are associated with MultiSim Design. The contents of these files cannot be read by a human; only a computer program can interpret the data. MS9 files are between 29 KB and 430 KB in size. The file type was developed 10 years ago and is still in use today. The files contain the following words: MSMCompressedElectronicsWorkbenchXML, eP7+f and hp$x. Some examples of file names are [DENEY] EDL-rapor02.ms9 or Circuit1.ms9. Such files sometimes refer to rapor and deney.

All other MS9 files (2%) have no uniform format. If you want to find out what your MS9 file contains, drag and drop it onto this page.
