A TMO file does not operate like familiar documents such as PDFs, photos, videos, or Word files that people edit and treat as primary information, because a TMO file is made by software rather than humans and loads in the background as part of internal workflows, storing things like timing metrics, performance details, or other derived information used to speed up the application, with the essential data kept in other files while the TMO merely supports the process.

Because of this role, the ".TMO" extension is not tied to a universal format, since different programs may use it for entirely unrelated purposes with completely different structures, meaning two TMO files from separate applications might have nothing in common, which explains why no generic "TMO opener" exists and why Windows prompts for a program when you double-click one—a clear sign it wasn’t meant for direct user access; and although you can technically open a TMO file in a text or hex editor, the data is usually serialized and meaningless without the original software’s rules, making manual edits risky enough to corrupt the file and break the program.

This is why removing a TMO file is generally less risky than modifying it, since many TMO files are nonessential support files that programs rebuild automatically when absent, leading only to slightly slower startup times, while editing can corrupt them in ways the software cannot repair; and the folder they appear in helps reveal their purpose—cache or temp folders usually hold disposable files, installation or game directories often contain necessary ones, and project folders indicate files meant to be handled solely through the software’s own controls.

The most practical way to understand a TMO file is as an internal work artifact rather than readable content, acting more like a cache entry, shader compilation output, or index file designed to optimize program behavior, shifting the focus from "How do I open it?" to "What application generated it, and is it meant for user interaction?" since such files exist to store CPU-intensive or memory-heavy results so programs can resume quickly and avoid repeating complex computations—essentially functioning as shortcuts the software creates for itself.

Another major reason is the separation of concerns, where developers categorize important stored information as information that must be preserved and derived data as information that can be recreated, with TMO files typically being derived, giving programs the flexibility to rebuild them and enabling safer crash handling since invalid or corrupted TMO files can be discarded on restart and regenerated from reliable inputs, lowering the risk of permanent damage to user data.

From a software engineering perspective, these files facilitate smooth iteration and version changes since internal data layouts shift over time, and locking temporary state into permanent formats would hinder backward compatibility; instead, TMO files keep that data disposable so programs can drop outdated versions and rebuild them automatically, and they also support automation by holding runtime snapshots or processed data that enable efficient pausing or parallel execution, with their replaceable design ensuring software remains fast, stable, and resilient through an erasable working scratchpad.
