Importing Contact data files into ACT from old hard drive

My hard drive crashed in November 2019.    I bought a new hard drive and had a computer service 

tech restore all my data to a new hard drive. 

I had my CRM data in an old version of ACT.   I since purchased ACT365 and I need to import my contact data into ACT365.  The files appear to be DBF, TDB and BLB files.  

I am not a computer expert, and I need some guidance as most of the import instructions tell me to transfer 

from xls files.      Any guidance would be helpful.   thank you,

JF
