An ARH file isn’t limited to a single definition, so context is the most reliable clue; one common source is Siemens ProTool, where ARH acts as a packaged HMI project for storage, transfer, or backup—typical if it originated from factory systems or directories referencing Siemens, ProTool, WinCC, STEP7, S7, or HMI—while another possibility is ArheoStratigraf, an archaeology tool where ARH files store stratigraphy documentation and diagrams like Harris Matrices, usually found in excavation folders labeled contexts, trench, layers, or matrix.

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 `.

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 single-purpose file type because ".ARH" isn’t controlled by a global standard and is reused across unrelated software, meaning two files with the same extension may contain totally different structures; context is the key—Siemens automation projects typically use ARH as a compressed HMI package, whereas archaeological setups use it as an ArheoStratigraf project—and proper identification comes from examining its origin, surrounding files, and whether it behaves like an extractable archive.

In real use, ".ARH" functions more as a label than a format, 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 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.
