A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .psyexp Files
PSYEXP files are XML-based files used by the PsychoPy 2 Experiment framework. They follow the MIME type text/xml and are written in plain text.
Their primary purpose is to store experiment configurations in psychology and behavioral science. They include details such as experimental design, stimuli settings, trial sequences, and response mappings.
- Experiment Design: Holds structured data like stimuli, timing, and participant responses.
- Experiment Execution: Provides a blueprint that PsychoPy reads to run experiments.
- Editability: Being XML, these files can be manually edited in a text editor.
According to FilExt.com, PSYEXP is the standard file format for PsychoPy experiments and is a key component in designing replicable research protocols.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
How do I open a .psyexp file?
You should use the PsychoPy Builder interface, which is part of the standalone PsychoPy installation. While the file technically uses the /text/xml MIME type, it is designed to be interpreted visually by the PsychoPy software rather than read directly.
Can I edit a .psyexp file in a text editor?
Yes, since the file is formatted as plain XML, you can view and edit it with tools like Notepad++, Visual Studio Code, or Sublime Text. However, manual editing is risky; accidentally breaking the XML tags or structure may prevent PsychoPy from loading the experiment correctly.
How do I convert a .psyexp file to a Python script?
Open the file in the PsychoPy Builder view and click the "Compile Script" button (usually an icon looking like a document with Python code). This generates a standard .py file that executes the experiment logic defined in your visual project.
Why am I getting errors when opening an older .psyexp file?
PsychoPy updates sometimes change how components are defined in the XML structure. If a file created in an older version fails to open, try changing the "Use Version" setting in the experiment settings to match the original version, or update your current PsychoPy installation.
Are .psyexp files compatible across different operating systems?
Yes, these files work on Windows, macOS, and Linux versions of PsychoPy. To ensure a smooth transfer between systems, always use relative paths for your stimuli resources (images, audio files) within the experiment settings rather than absolute hard-drive paths.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
