What is a PR1 file?

PR1 files mostly belong to PADS Layout. A PR1 file can represent different data types depending on its origin.

PCB Design File: This file type is used for electronic circuit board layout. It contains design data such as schematics, placement, routing, and board layers. Files of this kind are associated with Polar Instruments and are managed with software like PADS Layout.

MIME Email Message: Some PR1 files follow the MIME format. They are used by applications such as Microsoft Outlook and can sometimes be linked to PrimoCache data storage.

ETS2 Project File: In other cases, a PR1 file stores data for an ETS2 game mod package. This type is used with tools for modifying or managing ETS2 projects, including those tied to ETS2 Telemetry Server.

FilExt.com note: Determine the file’s origin to decide which application will open it correctly.

How to open a PR1 file

PR1 file extension format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the PR1 files:

The PR1 file extension is rarely used and is used by a few programs, each with its own file format. However, the following two file formats are common:

40% of all PR1 files use the same file format, which can be identified by the letters "39 00 08 00" at the beginning. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. A typical file size is 20 KB. This file type is based on cutting-edge technology.
10% of all PR1 files store the data in the MIME file format. MIME is short for Multipurpose Internet Mail Extensions. It is an Internet standard that extends the format of email messages to support Unicode and attachments. The contents of these files are easily readable with a text editor. A typical file size is 13 KB. Certain words are almost always found in the files, such as ----SD--3ed4f528-c0, Content-Type: multipart/related;, MIME-Version: 1.0, This is a multi-part message in MIME format, boundary="--SD--3ed4f528-c037-11d2-9d6d-0060b01ac6c5--"; and type="text/html".

The remaining 50% of all PR1 files are different files with different signatures. You can get all the details of your PR1 file by dragging it onto this page or by clicking the button "Choose your .pr1 file to analyze" above.
