An ARH file is not tied to one specific software ecosystem, so identifying it depends on where it appeared; many ARH files are Siemens ProTool HMI project packages used to store or move automation configurations—likely if associated with Siemens, ProTool, WinCC, STEP7, S7, or factory equipment—whereas others belong to ArheoStratigraf in archaeology, where they store stratigraphy and Harris Matrix information, usually found in documentation folders mentioning layers, trench, matrix, or contexts.

To identify your ARH file correctly, the easiest practical test is opening it with 7-Zip or WinRAR because some ARH files function as archives; if it opens and lists files or folders, you can extract and examine items like images, configs, project data, or databases—often indicating a Siemens/ProTool package—while if it doesn’t open, the file may still be valid but proprietary to ProTool or ArheoStratigraf, and you can further test by copying the file and renaming it to `.zip` or `.

Because many ARH files bundle entire projects, they may be stored as compressed containers, so opening them with 7-Zip or WinRAR is a smart first step; if they open, you’ll see folders with configs, databases, images, or logs that quickly identify the source, and you can extract assets directly, but if they don’t, the ARH may just be a proprietary format, and copying and renaming the extension to `.zip` or `.rar` can reveal whether it’s a standard archive, making this test an easy way to classify the ARH and possibly recover data.

An ARH file isn’t a fixed-format document because many developers reuse ".ARH" for unrelated purposes, so the extension alone tells you little; instead, the source matters—industrial automation work (Siemens/HMI/PLC) points toward a packaged project, while archaeological stratigraphy work points toward an ArheoStratigraf file—and checking how it behaves in tools like 7-Zip helps determine whether it’s an archive or a proprietary project.

What this means in practice is that ".ARH" acts as a name tag rather than a true format, because multiple unrelated programs can reuse the same suffix; an ARH from industrial automation might be a Siemens/ProTool HMI package holding screens, tag databases, alarms, and configs, while an ARH from archaeology may instead be an ArheoStratigraf project storing stratigraphy/context relationships and diagram layout data, so even filenames like `project.arh` can hide completely different contents, making context—source, neighboring files, and tests like 7-Zip—the safest way to identify whether it’s an extractable archive or a proprietary project.

You can typically pinpoint the type of ARH file by examining the *surrounding clues*—folder names, companion files, and the workflow source—since the extension itself is not definitive; in automation contexts with Siemens, ProTool, WinCC, STEP7/S7, PLC, HMI, tags, or alarms present, the ARH is likely a Siemens ProTool project package, whereas in archaeology folders labeled trench, context, stratigraphy, matrix, layers, or site and bundled with excavation documents or images, it is probably ArheoStratigraf, and if uncertain, attempting to open it with 7-Zip will reveal whether it behaves like an archive or needs its original software.
