I see that TCMD has an INI file in C:\Users\CWBillow\AppData\Local\JPSoft\TCMD.INI.
Is that the only file I need to save in order to backup TCMD and TCC settings?
First, note that your .INI file is located in the default location. I keep mine in my TCMD directory. How do you know where your TCMD.INI file is located? Use the %_ininame internal variable.
I also backup my 4start.btm file, nowadays called TCSTART.BTM, but I am from the old 4DOS days, and have still kept using the same name. I also keep this in my TCMD directory.
I also backup my alias.lst and function.lst files. These contain the definitions for my aliases and functions that I load each startup. Again, I also keep these in my TCMD directory.
If you are upgrading from a previous version of TCMD, I personally recommend NOT copying your TCMD.INI file over the newly created TCMD.INI file, as this only causes problems.
