Help importing files of specific types

I have the code below which imports all filetype .MOV files into the sheet. I would like to extend this to include other filetypes from a list of filetypes this could be any number from 2 upwards, presumably I would also have to cover the fact that some might be upper case and some lower

The only way I know how to do it would be to count the number of lines in the list then make the variable 'suffix' equal each one in turn in both upper and lower case then run through the code below for each one. No doubt this would work but it seems an inefficient way of doing it.

Can you suggest a better way?

suffix = ".MOV"
col = 25
rw = 3
   strFile = Dir(strpath)
    Do While Len(strFile) > 0
        
         If Right(strFile, 4) = suffix Then
            Cells(rw, col) = strFile
    
        Else
           rw = rw - 1
        
        End If
                
        rw = rw + 1
        strFile = Dir
    Loop
