File created by LabVIEW, a scientific measurement program used to interact with hardware devices; contains a menu that includes application items and custom user items; used to display virtual instrument (.VI) functions and operations. RTM files must be referenced by a virtual instrument (VI) in order for the run-time menu to function correctly. Custom menus only appear while the VI is running. RTM files may be created using LabVIEW by selecting Edit ? Run-Time Menu within the Menu Editor.
The RTM file extension is also used in RGA - Reliability Growth Analysis and Repairable System Analysis Software Tool from ReliaSoft. One of its default file types.
