About .3pm Files
3PM files are plain text documents formatted with Roff (troff) macros.
They are commonly used to create manual pages and documentation for Perl modules on Unix-like systems.
- Primary Use: Formatting and presenting manual (man) pages.
- MIME Type: Recognized as text/troff, which is standard for Roff-formatted files.
- Usage Details: They contain troff commands to control text layout and style.
- Software: Can be processed or viewed with tools like groff, troff, or Unix-based man page viewers.
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
What is a .3pm file?
A .3pm file is a manual page specifically for Perl modules on Unix-based operating systems. It contains plain text formatted with troff macros, which the system's man command uses to display structured documentation for Perl libraries.
How do I open a .3pm file on Linux or macOS?
You can view the formatted documentation by using the terminal command man ./filename.3pm. Alternatively, because the file is plain text, you can open it in any text editor like Vim, Nano, or Gedit to view the raw source and formatting codes.
Can I view .3pm files on Windows?
Windows does not natively support the man command used to render these files. However, you can open them with a text editor like Notepad++ or Microsoft Notepad to read the content, or use the Windows Subsystem for Linux (WSL) to view them properly formatted.
How can I convert a .3pm file to PDF or HTML?
You can use the groff utility to convert these files into more portable formats. For example, running groff -man -Thtml filename.3pm > output.html creates a web page, while using -Tpdf generates a PDF document.
What is the correct MIME type for .3pm files?
These files are identified by the MIME type text/troff. This classification tells web servers and browsers that the file is a text document containing Roff formatting instructions.
Is it safe to delete .3pm files?
If these files are located in your system's /usr/share/man directories, deleting them will remove the documentation for installed Perl modules. While this won't break the software itself, it will prevent you from accessing the help manuals via the man command.
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.
