What is an RCH file?

RCH files mostly belong to SWAT.

SWAT Output File: This RCH file often holds simulation data from the Soil and Water Assessment Tool. It records information from river reaches such as flow, sediment, and nutrient loads. For more details, visit the SWAT website.

3D Model File: In other cases, the file stores 3D model data. It can be associated with platforms like Autodesk Revit Cloud Worksharing, Autodesk ReCap, and even Ren'Py projects, holding geometric and design information.

How to open RCH files

You need a suitable software like SWAT to open an RCH file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your RCH file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a RCH file directly in the browser:. Just drag the file onto this browser window and drop it.

RCH file extension format:

A file format defines how the data in the file is structured. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the RCH files looks like this:

RCH is rarely used as a file extension and includes different formats for different programs. The two most popular formats are as follows:

• 30% of all RCH files use the same file format, which can be identified by the letters "1 SWAT " at the beginning. If you open these files in a text editor, you can view and read the content yourself. The files are often between 740 KB and 1 GB in size. The file type was developed only in the last few years. The following keywords are characteristic: 0   0, General Input/Output section (file.cio) and SWAT. Examples of file names are output.rch.
• 35% of all RCH files start with the magic bytes ADSKRCSS, which are always the first bytes of this file format. The contents of these files cannot be read by a human; only a computer program can interpret the data. RCH files can be up to 77 MB in size, but are often around 1 MB - 28 MB. Certain words are almost always found in the files, such as ADSKRCSS. The following filename is common: fc62342c-94ae-4df8-8f02-fe2969f6def5-preview.rch. These files can be linked to preview.

All the rest of the RCH files (35%) have different formats. Sometimes used for bcbb. Drag & drop your file here to see the file format and a preview of your RCH file!
