MATLAB: ‘Unable to open file’ error with importdata

#importdata #.txtMATLAB

I am trying to import data from a .txt file with the same structure as below
with the code below, I am looking for a .txt file and I try to save each column in a matlab file but matlab tells me 'Unable to open file'
[filename,pathname]=uigetfile({'*.fl.txt' 'Torque file (*.fl.txt)'},'Select a torque curve');
            
            if filename ~= 0
            
                Spill = importdata(filename);
                extracted=Spill.data
                CDC_N=extracted(:,1)
                CDC_Torque=extracted(:,2)
                save('CDC.mat','CDC_N','CDC_Torque');
            
            end
if anyone could help me, I'd be grateful.
thanks

Replacing 
Spill = importdata(filename);
with
Spill = importdata( fullfile( pathname, filename );
may help.
