TCL File

Did your computer fail to open a TCL file? We explain what they are used for and recommend software that we know can open or otherwise handle your .TCL files.

What is a TCL file?

The TCL file extension indicates to your device which app can open the file. However, different programs may use the TCL file type for different types of data.
