There are three formats for storing OSI messages in trace files:
- *.osi
-
Native binary trace file.
- *.txth
-
Human-readable plain-text trace file.
- *.mcap
-
Binary trace file supporting more advanced features like indexed data, additional metadata and more.

Note
|
Previous releases of OSI also supported a so-called plain-text trace file format, with file extension .txt.
This legacy format did not contain plain-text, but rather binary protobuf messages separated by a special separator.
For obvious reasons the format was deprecated and fully replaced with the .osi binary file format.
This release no longer contains any support for the legacy .txt file format.
These files may be used for manual checks.

Tip

For efficient handling of trace files, you can utilize the specification-compliant tools and libraries provided in the companion osi-utilities repository. For example, convenient writer and reader classes are provided handling OSI messages for the different file formats. |
