Have you encountered a problem with a P3M file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a P3M file here. In the further part of this page we have added a list of programs that should open your P3M file. It is enough you choose a proper application for your operating system, download and install it.


The file extension P3M identifies default files for materials (textures) of the image editing software Adobe Photoshop. P3m files include the material and texture properties, such as gloss, reflection, and how to lay a 2D texture on a 3D object.

These materials can be used to add surface features and textures to 3D objects in 3D scenes. The ability to work with 3D model data is only available in the extended version introduced since version CS3. Photoshop extended offers the possibility to import different 3D formats (eg 3DS Max) or to create objects yourself.

If you create a 3D layer, you have access to the various 3D settings windows. You can load P3M files (or select the defaults) and save them in '3D (Materials)'.

P3M files are usually placed under 'Preferences / Materials' in the main Photoshop folder. By default, various specifications are already installed. (eg wood, steel, chrome)

How to open a P3M file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the P3M file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a P3M file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support P3M files. At this point we are looking for disk space where the application was installed in and we can link it with a P3M file. Since then, our operating system will use the selected program to support all P3M files.

Other issues

Despite the described problem with P3M there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the P3M file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the P3M file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
