What is a MOP file

MOP files mostly belong to JetBrains Rider. MOP files are not a single type of file. Their purpose depends on the software that created them.

JetBrains MPS files: These use a JetDB internal format and are handled by JetBrains Rider. They often store floor plan data such as seen in Furukawa PlantMate. Visit the JetBrains Rider website for more details.

PCB design files: These files contain circuit board layout information. They are used by programs like Altium Designer and are similar in function to Mentor Graphics Pad files. More information is available at the Altium website.

Game model files: These are used in game development to store 3D mesh object data. They appear in projects such as The Witcher 3: Wild Hunt and may be associated with tools like MOPAC. Check The Witcher website for details.

MirrorOp device list files: These use an XML format and hold device or configuration data for MirrorOp Receiver.

FilExt.com tip: The file’s functionality depends on its source. Inspect the file header or open it in a text editor to look for XML tags or other format indicators to decide which software is needed.

How to open a MOP file

You need a suitable software like JetBrains Rider to open a MOP 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 MOP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MOP file directly in the browser:. Just drag the file onto this browser window and drop it.

MOP 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 first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. In the following you will find our evaluation of the MOP files:

The MOP file extension is rarely used and is used by a few programs, each with its own file format. However, the following two file formats are common:

25% of all MOP files use the popular JetDB file format. The JetDB is a database format often used by Microsoft Access and Visual Basic programs. JET is short for Joint Engine Technology. These files are binary files, so they do not contain text, but only cryptic characters. The files are on average 1 MB in size and range from 1.3 MB to 1.6 MB. The keywords Standard Jet DB are typical for these files.
10% of all MOP files are MOP report files. The contents of these files are easily readable with a text editor. The files are 6 KB to 8 KB in size, with a median of 7 KB. Certain words are almost always found in the files, such as # ============, DESCRIPTION "", DESIGN_TYPE PCB_DESIGN, DEVICETYPE 1, MOPFILE 2, OUTPUT_TO FILE, PLOT_TYPE ARTWORK, PLOTENABLED Y, VARIANTNAME "", PLOT "Top Silkscreen" and LAYER SIDE SIDE_TOP LAYERTYPE.

All other MOP files (65%) have no uniform format, such as GFF and AUX. Often described as setup, monsters or noname. You can get all the details of your MOP file by dragging it onto this page or by clicking the button "Choose your .mop file to analyze" above.

How to solve problems with MOP files

Associate the MOP file extension with the correct application.
Update your software that should actually open design files. Because only the current version supports the latest MOP file format. Search, therefore, e.g. on the manufacturer website after an available JetBrains Rider update.
To make sure that your MOP file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
