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.
