The tch file extension is associated with Borland C++, an integrated development environment from Borland for developing programs in the C++ programming language.
A tch file stores help content used by the environment's documentation and help system. It is a supporting document file rather than a C++ source or project file.
Open the tch file from the corresponding Borland C++ installation on Microsoft Windows. The Borland C++ help system is the appropriate program for viewing its contents.
