An XRF file reflects whatever the generating tool designed because the extension isn’t globally managed; frequently it contains X-ray fluorescence measurements such as sample metadata, instrument settings, calibration modes, and element concentrations in ppm or %, but in other contexts it behaves like a project/session container similar to a PSD or DWG that holds spectra, templates, notes, and multiple samples in either binary or packaged form, so determining what it truly is depends on its source device or program, Windows associations, and whether opening it in a text editor reveals readable data or not.

An XRF file doesn’t inherently describe its structure since ".XRF" isn’t controlled by any universal authority, so different companies reuse it freely; frequently it’s tied to X-ray fluorescence results containing sample identifiers, timestamps, operator names, device models and settings, the calibration mode used, and the resulting element list (Fe, Cu, Zn, Pb) with values in ppm or %, sometimes accompanied by uncertainty, limits of detection, pass/fail hints, or included spectral/peak data.

However, an XRF file may also be a full project/session file instead of a plain report, designed for reopening inside the originating app and capable of storing multiple samples, saved settings, templates, notes, and linked spectra or images, which makes it larger and typically binary; to identify it, look at the file’s source, check Windows’ associated program, and open it in a text editor—structured XML/JSON/CSV-like text or keywords like "Element," "ppm," or "Calibration" signal a readable export, while random characters usually indicate a binary container requiring the vendor tool.

The real meaning of an XRF file is defined by its origin, not the extension because extensions are freely reused, so ".XRF" carries no universal guarantee; in some contexts the file stores X-ray fluorescence results including sample IDs, timestamps, calibration modes, and element readings with ppm/% values, uncertainties, or spectral data, while in others it functions as a proprietary project/session file bundling multiple runs, settings, templates, and resources, which can make it appear as unreadable binary, and understanding which type you have depends on evidence such as its creator, its default opener, readable XML/JSON/CSV-like structures, ZIP-like magic bytes, or the presence of companion export formats.

An XRF file in the elemental-analysis sense represents the collected metadata plus computed concentrations, since XRF instruments estimate composition from emitted X-rays; these files usually store sample naming details, operator/timestamp info, notes or location, as well as instrument specifics—model, detector type, duration, tube settings—and the calibration/method mode (alloy, soil/mining, RoHS) that governs spectrum interpretation; the key output is a list of elements (Fe, Cu, Zn, Pb, Ni, Cr, Mn, etc.) with concentrations in ppm or %, sometimes supplemented with uncertainty, LOD, flags, or pass/fail results, and some formats include spectral or peak data and correction steps, with vendor choices determining whether the file appears readable or binary.
