IYh Dear Ancy G C

"tfh" files could potentially refer to a TensorFlow file format. TensorFlow is a popular open-source library for machine learning and deep learning. It uses various file formats to store trained models, checkpoints, and other data.

You can try using TensorFlow itself or TensorFlow-compatible software to open and analyze it, eg https://runcode.io/tensorflow-online-coding-platform

Daniyel Yaacov Bilar Thank you so much for your response. While searching for tfh file format, I learned that the file extension is associated with turbo profiler, a program developed by Borland Corporation. Does anyone know about it?

IYH Dear Ancy G C

That's some old software :D

OK, here is a 1990 manual on Borland Turbo Profiler https://doc.lagout.org/science/0_Computer%20Science/0_Computer%20History/old-hardware/borland/turbo_assembler/Turbo_Profiler_1.0_Users_Guide_1990.pdf

If you have some tech savvy and the right emulated environment you can likely run the Borland Profiler software and read your files. The sw can be found here https://archive.org/details/borland-turbo-debugger-profiler-assembler
