What is an RTM file?
The .RTM file extension has multiple technical uses. Most commonly, it is a Report Template file used by Delphi-based reporting tools. Software like Digital Metaphors ReportBuilder and AutoCount Accounting use .RTM files to store page layouts, data fields, and visual styling for printable documents.
However, .RTM is also a LabVIEW Run-Time Menu File created by National Instruments to customize user interfaces. Other completely different uses include Windows side-by-side assembly files and manifests for Microsoft Visual C++, maritime navigation route files for Transas ECDIS systems, and 3D skeletal animation data files for Bohemia Interactive games like Arma 3.
How to open RTM files?
Because .RTM files have so many possible formats, opening them requires the correct creator software. Report templates open in ReportBuilder or related accounting tools. LabVIEW menu files require LabVIEW. Game animation files require specialized modding tools for the Arma engine. Visual C++ .RTM files are core system components managed automatically by the Windows operating system.
Identify and Inspect with viewer.online
viewer.online/rtm can analyze .RTM files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. Since .RTM has multiple possible meanings, we strongly recommend using viewer.online/rtm to identify the actual format of your file before attempting to open it elsewhere.
Conversion and Best Practices
If you need to share report layouts or extract standard data, you will likely need to convert the file. We recommend converting .RTM report templates to universal target formats like .PDF, .HTML, or .CSV using convert.guru.
Summary
Ultimately, viewer.online/rtm is useful for identifying, inspecting, and understanding .RTM files without installing specialized reporting software, game engines, or dealing with compatibility problems.
