how to open old MatLab files with .sfit extension?

Due to the fact that my company have anti-virus active during the install, I took the recommendation to just install MatLAB basic- r2019a

Now, my user said:

"unable to open any of our old MatLab files (.sfit extension). Do I need to install an additional module in order to work with these type of files?"

Please advise.

Thanks, Immaculata
