Absolutely.  If Import is not appropriate, look at Get or Read.  Assuming your 
data is in a plain text file with columns separated by spaces, you can use 
something like the following:

data = Import["C:\\My Path\\data.txt","Table"];

If you want to plot the data in column 4 vs. column 1, you can use something 
like:

ListPlot[data[[All,{1,4}]]];

If you want to plot both columns 4 vs. column 1 and column 6 vs. column 2 on a 
single graph, you can use something like:

<<Graphics`MultipleListPlot
MultipleListPlot[ data[[All,{1,4}]], data[[All,{2,6}]]];

Take a look at the help for Import to see the multitude of file types you can 
import.
