I have a very large (16Gb) CSV file that contains one column with data separated by semicolumn.
I only need 2 columns from this data, but I cannot read it first since the memory is running out (I have 16Gb ram).
Is it possible to somehow separate the semicolumn to a column and read only the data I need (which is 2/6 columns)?

Use 'delimiter', ';', and 'SelectedVariableNames' with a vector that is the two column numbers.
