What is a .OTMU file?
An .OTMU file is a special kind of document used by a program called Origin, which is a tool for people like scientists and engineers who need to analyze data and make graphs. Origin 2018 and newer versions use this file type. The "OTMU" stands for Origin Unicode Matrix Template. Think of it as a blueprint or a pattern for making a specific type of graph known as an .OGMU graph.
Inside an OTMU file, there are settings and instructions. These include how many sheets are in the file, how big each sheet is (meaning how many rows and columns it has), certain math operations that can be performed, and what the graphs should look like (their format and style). It's like having a recipe that tells Origin exactly how to create a graph so that you don't have to set it up from scratch every time.
To open an .OTMU file, you need to have the OriginLab Origin program. This is the software that understands how to read the instructions inside the OTMU file and use them to create graphs. Without Origin, your computer wouldn't know what to do with an OTMU file because it's designed specifically for use with that software.
