EROSION 3D uses the PR file as a settings file for precipitation parameters. These parameters provide rainfall information used when the software models soil erosion and related processes.
The PR file belongs to the EROSION 3D file set and is intended to be used by the application rather than as a general-purpose document. EROSION 3D is available for Microsoft Windows.
Open the PR file in EROSION 3D on Microsoft Windows. The software should read the file as part of its precipitation or simulation settings rather than opening it as a normal document.
A text editor may display the file's contents, but changing it outside EROSION 3D can make the parameters invalid or unusable.
PR files are application-specific parameter files and do not have a meaningful general-purpose conversion format. They should normally remain in the format expected by EROSION 3D.
To use the precipitation data elsewhere, open the file in EROSION 3D and use an available export function, if the software provides one, rather than converting the PR file directly.

W32/Brontok-DP is a computer worm that targets Microsoft Windows. A file with the .pr file extension may be part of the worm or may be identified by antivirus software as one of its files.
The file is intended for use by the malicious software rather than for opening in a standard application. Antivirus products such as AVG Antivirus, Norton Antivirus, BitDefender, Kaspersky Anti-Virus, and Avast Antivirus for Microsoft Windows can detect or remove this threat. The extension does not represent a legitimate document format.
Do not double-click or otherwise try to open a suspected W32/Brontok-DP file. Disconnect the affected Microsoft Windows computer from networks if appropriate, then scan the file and the computer with an up-to-date antivirus program.
AVG Antivirus, Norton Antivirus, BitDefender, Kaspersky Anti-Virus, and Avast Antivirus are associated with this file on Microsoft Windows. Follow the selected program's instructions to quarantine or remove the detected threat.
A W32/Brontok-DP worm file cannot be usefully or safely converted. It is not a document containing user data, and conversion would not make it safe.
Use antivirus software to identify, quarantine, or remove the file instead of sending it to a file converter or attempting to export its contents.
