About PLM files

The .PLM extension represents three distinct file formats, creating a common source of confusion. The most critical use case is as a Radiological Plume Model, a data container generated by environmental safety tools like HotSpot (developed by LLNL) or the EPA ALOHA software. These files store complex atmospheric dispersion data used to predict the spread of hazardous materials. Because they are highly specialized binary or proprietary text formats, they cannot be opened in standard office software like Microsoft Excel. Users typically need to convert these models to PDF for official safety reports, CSV for raw data analysis, or KML for GIS mapping.

Alternatively, a .PLM file may be a Panasonic SD-Voice Playlist, used by older voice recorders to organize audio tracks on SD cards. These are incompatible with modern players like VLC Media Player and are best converted to standard M3U playlists. Finally, in legacy computing, .PLM serves as a source code file for PL/M (Programming Language for Microcomputers), a 1970s language by Intel. These strictly require a text-based conversion to TXT or PDF to be legible on modern systems without a CP/M emulator.

Convert.Guru analyzes your PLM file, detects the exact format, and lets you read the text inside.

Users also converted PML, GPX, STC and EXF files.
