What is an LTT file?

LTT files mostly belong to Monotype Font Linking Utility. LTT files can refer to two different file types depending on the system that creates them.
Monotype Font Linking Table:
This version of a LTT file is used by font management systems. It holds data that maps fonts to specific character sets. This file is part of the process that a utility such as the Monotype Font Linking Utility uses to ensure that the correct fonts are applied when needed.
Log Trace Text:
Another use for a LTT file is to record log trace information. In this case, the file is generated by systems like HP LTT or tools related to LTTng. It keeps plain text records of system events or debug information.
If you have a LTT file, you can usually view its contents with a simple text editor. Use Notepad or another basic editor to check the file content.

For Font Linking: It contains mapping information for fonts.
For Log Tracing: It stores event or debug logs in text form.
