FileMagic: Expert Support for ARH Files

An ARH file has multiple possible interpretations, 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 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 `.zip` or `.rar` to see whether it extracts, with the best opening strategy depending on your needs: if you only want assets, extraction may be enough, but proper viewing/editing requires the original program.

Because many ARH files store data in archive-like containers, 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 serves different roles depending on context since ".ARH" is a reused, non-standard extension; determining its type depends on its origin—industrial automation environments use ARH for packaged HMI/PLC projects, and archaeology uses it for ArheoStratigraf data—and checking whether it extracts in 7-Zip helps confirm if it’s an archive or proprietary.

What this means in practice is that ".ARH" labels the file but doesn’t define its structure, 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.
