Saving multiple files in one folder

Hi, Please how can I save multiple figurea as png into a single folder? I tried this although is "fig" but it only save the last image.

path = 'C:\fig_test' ;
N = 6 ;
for k = 1:N
    
    % theta vs x at point x=0 and y=0
    figure(1)
    hold on
    lgd = ['\xi = ',num2str(xivals(i))];
    plot(xarray, squeeze(theta(i, yl, 1:nx, nt)), 'DisplayName',lgd)
    xlabel('y[m]')
    ylabel('\theta [rad]')
    xlim([xmin xmax])
    hold off
    legend('Location','best')
    % velocity in x-direction vs y
    figure(2)
    hold on
    plot(yarray, u(i, 1:ny, xl, nt), 'DisplayName',lgd)
    xlabel('y[m]')
    ylabel('u [m/s]')
    hold off
    legend('Location','best')
    % velocity in y-direction vs y
    figure(3)
    hold on
    plot(yarray, squeeze(v(i, 1:ny, xl, nt)), 'DisplayName',lgd)
    xlabel('y[m]')
    ylabel('v [m/s]')
    hold off
    legend('Location','best')
    % theta vs time at x=0 and y=0
    figure(4)
    hold on
    plot(tarray, squeeze(theta(i, yl,xl, 1:nt)), 'DisplayName',lgd)
    xlabel('time [sec]')
    ylabel('\theta [rad]')
    hold off
    legend('Location','best')
    % theta vs x at x from 251 to 301 and y=0
    figure(5)
    hold on
    plot(xarray(251:301), squeeze(theta(i, yl, 251:301, nt)), 'DisplayName',lgd)
    xlabel('x [m]')
    ylabel('\theta [rad]')
    hold off
    legend('Location','best')
    % velocity in x-direction vs x at x from 251 to 301 and y=0
    figure(6)
    hold on
    plot(xarray(251:301), squeeze(u(i, yl, 251:301, nt)), 'DisplayName',lgd)
    xlabel('x [m]')
    ylabel('v [m/s]')
    hold off
    legend('Location','best')
    filename = [path, filesep, 'myfigure',num2str(k)] ;
    savefig(filename)
end

figpath = 'C:\Users\8765309\fig_test' ;

% theta vs x at point x=0 and y=0
figure(1)
hold on
lgd = ['\xi = ',num2str(xivals(i))];
plot(xarray, squeeze(theta(i, yl, 1:nx, nt)), 'DisplayName',lgd)
xlabel('y[m]')
ylabel('\theta [rad]')
xlim([xmin xmax])
hold off
legend('Location','best')
% velocity in x-direction vs y
figure(2)
hold on
plot(yarray, u(i, 1:ny, xl, nt), 'DisplayName',lgd)
xlabel('y[m]')
ylabel('u [m/s]')
hold off
legend('Location','best')
% velocity in y-direction vs y
figure(3)
hold on
plot(yarray, squeeze(v(i, 1:ny, xl, nt)), 'DisplayName',lgd)
xlabel('y[m]')
ylabel('v [m/s]')
hold off
legend('Location','best')
% theta vs time at x=0 and y=0
figure(4)
hold on
plot(tarray, squeeze(theta(i, yl,xl, 1:nt)), 'DisplayName',lgd)
xlabel('time [sec]')
ylabel('\theta [rad]')
hold off
legend('Location','best')
% theta vs x at x from 251 to 301 and y=0
figure(5)
hold on
plot(xarray(251:301), squeeze(theta(i, yl, 251:301, nt)), 'DisplayName',lgd)
xlabel('x [m]')
ylabel('\theta [rad]')
hold off
legend('Location','best')
% velocity in x-direction vs x at x from 251 to 301 and y=0
figure(6)
hold on
plot(xarray(251:301), squeeze(u(i, yl, 251:301, nt)), 'DisplayName',lgd)
xlabel('x [m]')
ylabel('v [m/s]')
hold off
legend('Location','best')

    
N = 6 ;
for k = 1:N
    filename = fullfile(figpath, "myfigure" + k + ".fig"] ;
    savefig(k, filename)
end

Hi Walter thank you for your help. It worked but is still saving the last figure only.

Hi Walter,

Thank you I have been abel to do using this:

FigList = findobj(allchild(0), 'flat', 'Type', 'figure');
for iFig = 1:length(FigList)
    FigHandle = FigList(iFig);
    FigName   = ['Fig' num2str(iFig)];
    saveas(FigHandle, fullfile(figpath,  [FigName '.png']));
end

[Walter Roberson]

Corrected.
