A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .ldp Files
LDP files are text-based files with distinct uses.
They come in two main types based on their MIME type.
text/plain LDP files often contain export data from Altium Designer layer pairs. This data represents design layer information used in electronics projects.
text/ldpatch LDP files use the Linked Data Patch format. They hold patch instructions for updating linked data records.
- Altium Designer Export: These files are generated by Altium Designer for circuit layout projects. They store layer pair information in a plain text format.
- Linked Data Patching: These files carry commands to modify linked data. They are used in environments that work with connected data records.
Based on information from FilExt.com, LDP files are mainly used in technical fields and are straightforward to read and edit.
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 an LDP file?
An LDP file is a text-based document that usually serves one of two purposes: storing Altium Designer layer pair exports or containing Linked Data Patch instructions. Since both types are stored as plain text, their contents are human-readable.
How do I open an LDP file?
You can view the raw contents of any LDP file using a standard text editor like Microsoft Notepad, Apple TextEdit, or Notepad++. To use the file for its intended technical purpose, you should open Altium exports within Altium Designer or process Linked Data Patches with compatible semantic web tools.
What MIME type is associated with LDP files?
LDP files are often served as standard text/plain files, particularly when generated by Altium Designer. However, when used for Linked Data Patching, they should be identified with the specific media type text/ldpatch to ensure servers process the patch commands correctly.
Can I convert an LDP file to PDF?
Yes, because LDP files are simple text, you can convert them to PDF for easier sharing or documentation. Open the file in a text editor, select File > Print, and choose a "Print to PDF" option to save the output as a .pdf file.
What data is inside an Altium LDP file?
An LDP file generated by Altium Designer contains configuration data regarding Layer Pairs for a Printed Circuit Board (PCB) design. This text data defines how specific board layers are paired together, which is essential for design rule checking and manufacturing outputs.
Why is my LDP file not working in Altium Designer?
If the file fails to open, it may be a Linked Data Patch file rather than an Altium export. Open the file in Notepad to check the text; if it contains commands for modifying data records rather than PCB layer information, it is incompatible with Altium software.
How do I edit an LDP file?
You can edit LDP files using any code or text editor, such as VS Code or Sublime Text. However, manual editing is risky; modifying an Altium export incorrectly may break the layer configuration, and syntax errors in a Linked Data Patch will cause the update to fail.
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.
