An XRF file can refer to unrelated structures 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 follow one universal definition because “.XRF” isn’t governed by a single standard, meaning different software makers can reuse it for totally different purposes; however, many times it relates to X-ray fluorescence testing, where the file is an export containing elemental analysis details like sample ID, operator, timestamp, instrument model/settings, calibration mode (alloy, soil/mining, RoHS), and element results (Fe, Cu, Zn, Pb) in % or ppm, sometimes with uncertainty, detection limits, pass/fail flags, or even spectral/peak data.

However, an XRF file can act as a proprietary multi-sample project file instead of a straightforward results file, meaning it’s intended for internal reopening and may bundle samples, settings, templates, notes, images, and spectra in a binary form; the practical way to determine which type you have is to note its origin, inspect Windows “Opens with,” and test it in a text editor—legible XML/JSON/CSV-like layouts or words like “Element,” “ppm,” and “Calibration” point to a text-based export, whereas meaningless characters imply a proprietary binary that only the original software can interpret.
The real meaning of an XRF file is dictated by the source application because file extensions are merely labels that multiple vendors can reuse, so XRF files may store X-ray fluorescence data—sample identifiers, timestamps, method/calibration settings, elemental ppm/% tables, uncertainty or spectral details—or act as project/session containers bundling runs, settings, templates, and embedded assets that appear binary or archive-like in a text editor; therefore the correct interpretation comes from checking its creator, its associated program, whether any readable text structures appear, whether the header resembles a ZIP, and whether it sits next to shareable outputs like PDF/CSV.
An XRF file used for X-ray fluorescence results serves as a record of both the measurement context and the computed elemental values, because the analyzer estimates elemental composition from the sample’s emitted X-rays; such a file often includes sample identifiers, operator and timestamp info, notes, and sometimes location/site, as well as instrument details like model/serial, detector type, measurement time, and tube voltage/current, plus the calibration/method mode (alloy, soil/mining, RoHS), which determines how the spectrum is interpreted; its core output is the results table showing elements (Fe, Cu, Zn, Pb, Ni, Cr, Mn, etc.) with concentrations in % or ppm, along with uncertainty, LOD, warnings, or pass/fail indicators, and some formats embed full or partial spectral data and applied corrections, with readability varying by vendor—some exports appear as XML/CSV-like text while others are proprietary binaries.
