An ARH file isn’t governed by one universal format, making context crucial; in industrial automation it often belongs to Siemens ProTool as a compressed HMI project used for storage and backups, especially when found with Siemens- or PLC-related terms, while in archaeological workflows it may instead be an ArheoStratigraf project containing stratigraphy documentation and Harris Matrix diagrams, commonly appearing in excavation folders labeled layers, contexts, trenches, or matrix.

To determine what your ARH file actually is, the simplest first step is to try opening it with 7-Zip or WinRAR because many ARH files act as archive containers; if it opens, you can inspect the extracted contents—project directories, configs, images, databases—which usually hints at a ProTool-style packaged project, whereas a failure to open often just means it’s in a proprietary format requiring ProTool or ArheoStratigraf, and a useful trick is renaming a copy to `.

Because many ARH files are essentially compressed bundles, tools like 7-Zip or WinRAR are worth trying early, since they can instantly confirm whether the ARH is a browseable archive; if it opens, the internal files—project directories, configs, images, logs—usually reveal what software it belongs to, and you can extract items without needing the original app, while an inability to open typically means the format is proprietary, and renaming a copy to `.zip` or `.rar` can expose hidden archives, making this a simple way to identify the ARH and recover content.

An ARH file is not tied to a consistent internal structure because ".ARH" lacks a universal definition, so the most reliable way to identify it is by context—automation workflows (Siemens/HMI/PLC) typically mean a packaged project, while archaeological workflows mean ArheoStratigraf—and by observing whether it behaves like an archive in tools such as 7-Zip before choosing the proper software to open it.

In effect, ".ARH" acts as a superficial indicator, because the extension can belong to unrelated programs; one ARH might be a Siemens/ProTool HMI project holding screens, tags, configurations, and alarms, while another from archaeology might be ArheoStratigraf data describing stratigraphy relationships and diagrams, so identical-looking filenames can still differ entirely, and the most reliable identification comes from tracing its source and using tools like 7-Zip to see whether it behaves like an archive or needs its original software.

You can often identify an ARH file by looking at the *context it’s stored in*—neighboring filenames, folder themes, and domain clues—because the suffix alone doesn’t define the internal format; ARH files near automation-related items like Siemens, ProTool, WinCC, STEP7/S7, PLC, HMI, or engineering project versions are generally Siemens ProTool archives, while ARH files in archaeology directories referencing trench, context, stratigraphy, matrix, or layers and surrounded by site photos or context sheets usually belong to ArheoStratigraf, and testing with 7-Zip helps confirm whether it’s a container or a proprietary project.
