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 figure out the ARH type without guessing, the fastest method is using 7-Zip or WinRAR, since some ARH files are container archives; if the tool opens it and reveals internal structure, you can extract and check for project folders, configs, images, or databases—often tied to Siemens/ProTool—while an inability to open it doesn’t imply corruption but rather that it’s a proprietary project format requiring the original application, and an additional trick is renaming a copied version to `.zip` or `.rar` to test whether it extracts, with the correct opening method depending on your purpose: extraction may be enough for asset recovery, but full project access needs the creating software.

Because many ARH files behave like packaged projects, they’re often saved in compressed form, so checking them with 7-Zip or WinRAR is worthwhile even without knowing the program; if the archive opens, you’ll see internal folders containing configs, images, logs, or databases that reveal what created it, and you can extract assets immediately, while a failure to open usually means it’s a proprietary format, with a useful trick being to copy and rename the extension to `.zip` or `.rar` to see if it extracts, making this a quick, low-effort way to identify the ARH and possibly retrieve needed content.

An ARH file isn’t defined by a single universal meaning because ".ARH" is a non-standard extension reused by different software makers, so two ARH files may be completely unrelated even though they share the same suffix; the real clue is the context—industrial automation environments (Siemens, HMI/PLC) often use ARH as a packed project file, while archaeology workflows use it for ArheoStratigraf data—and identifying it relies more on the source workflow, nearby files, and whether it opens like an archive in tools such as 7-Zip.

Practically speaking, ".ARH" tells you almost nothing about the file’s structure, so an ARH from industrial automation might be a Siemens/ProTool HMI project with screens, tags, alarms, and configurations, whereas one from archaeology may be an ArheoStratigraf file holding context relationships and diagram setups; even identical filenames can hide totally different data, making context and archive tests (like opening with 7-Zip) the safest way to determine whether it’s an extractable package or a proprietary project.

You can usually tell what an ARH file represents by observing the *environment it lives in*—the folder structure, companion files, and domain—because the extension doesn’t dictate the format; ARH files appearing in automation engineering folders with Siemens, ProTool, WinCC, STEP7/S7, PLC, panels, tags, or alarms are commonly Siemens ProTool project packages, while ARH files inside archaeology folders marked trench, stratigraphy, matrix, layers, or excavation data typically correspond to ArheoStratigraf projects, and in ambiguous cases, a 7-Zip "Open archive" test reveals whether it’s a browsable container or a proprietary file requiring the original tool.
