An ARH file is a flexible extension used by unrelated tools, with one common usage being Siemens ProTool, where ARH files store packaged HMI project data for transfer or backup—expected in environments involving Siemens, WinCC, STEP7, or S7—while another usage is with ArheoStratigraf in archaeology, where the file holds stratigraphy records and diagram data like a Harris Matrix, typically located in folders referencing trenches, layers, contexts, or stratigraphy.

To identify what type of ARH file you have, the fastest practical check is to try opening it with 7-Zip or WinRAR, because some ARH files are just container-style archives; if 7-Zip opens it and shows folders or files, you can extract them and look for clues like project structures, databases, images, or configs—often indicating a packaged project (commonly the Siemens/ProTool type), but if 7-Zip can’t open it, the ARH may still be valid yet proprietary, requiring the original software such as ProTool or ArheoStratigraf, and a helpful trick is copying the file and renaming it to `.zip` (or `.rar`) to see if it’s simply an archive under a different name, with extraction possible if it opens, while the correct opening method depends on your goal: if you only need assets and it extracts cleanly you may avoid using the original tool, but to view or edit the full project you’ll usually need the application that created it.

Because many ARH files act like project packages, they’re sometimes stored as compressed containers similar to ZIP files, which is why trying 7-Zip or WinRAR is useful even before you know the source program; if 7-Zip opens it, you’ll usually see folders and files—configs, databases, images, logs—that reveal the file’s purpose and let you extract assets without the original software, while a failure to open simply suggests a proprietary format, and a good trick is renaming a copy to `.zip` or `.rar` to test whether it extracts, making this quick archive test an easy way to identify the ARH type and possibly recover what you need right away.

An ARH file doesn’t behave like a standardized file type 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.

In real use, ".ARH" is a reused extension rather than a fixed standard, allowing different software to assign it to unrelated data; thus an automation-sourced ARH might be a Siemens/ProTool HMI package containing screens, configurations, alarms, and tag databases, while an archaeology-sourced ARH could be an ArheoStratigraf project with stratigraphy links and diagram information, and similar filenames may mask these differences, so identifying it requires checking context and testing with tools like 7-Zip to distinguish between an archive and a proprietary project.

You can determine an ARH file’s nature by checking the *context around it*—folder names, neighboring files, and workflow—since ".ARH" can mean different things; when it sits in automation-related folders with Siemens, ProTool, WinCC, STEP7/S7, PLC, or alarm/tag references, it’s likely a Siemens ProTool compressed project, but when stored in archaeology folders referencing trench, stratigraphy, layers, or context numbers and surrounded by drawings, photos, or excavation spreadsheets, it’s probably ArheoStratigraf, and if still unclear, trying 7-Zip helps: archive-like behavior suggests a packaged project, and failure to open implies proprietary software is needed.
