About .pew Files
PEW files are binary files used with the BIS Visitor Project. They carry the MIME type application/octet-stream, which means they hold raw binary data rather than text.
- Primary use: Storing and processing project-specific data in the BIS Visitor Project.
- Data type: Contains non-readable, binary information meant for specialized software.
- Software: Requires dedicated applications from the BIS Visitor Project to open or modify the file. Standard text editors won’t display its content correctly.
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 .pew file?
You must use the BIS Visitor Project software to open this file. Because .pew files contain proprietary binary data, third-party viewers or standard office applications cannot read them. Ensure you have the correct version of the BIS software installed on your computer.
Why does the file look like scrambled text in Notepad?
PEW files are binary, not plain text. When you open a binary file in a text editor, the program attempts to decode the raw bytes as characters, resulting in unreadable symbols and "garbage" text. To view the content correctly, the file must be processed by the application that created it.
Can I convert a .pew file to PDF or Excel?
You generally cannot convert a .pew file directly using online converters. To get the data into a format like PDF or Excel, you typically need to open the file within the BIS Visitor Project application and use its built-in "Export" or "Save As" function.
What MIME type is used for .pew files?
The most common MIME type is application/octet-stream. This generic type indicates that the file contains binary data without a specific standard subtype. You can learn more about how systems handle this type at mime-type.com or by viewing the application/octet-stream page.
Is a .pew file dangerous?
A .pew file is a data file, but unknown binary files should be treated with caution. Since the file extension is uncommon and uses the generic application/octet-stream MIME type, email servers may block it. Always scan files from unknown sources with antivirus software before opening them.
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.
