How to save figures generated from function within a for loop?

i am looping over all data present in the desired folder, each loop of Extractdatafrom txt generates 3 figures and several arrays, how do i save only the figures generated from the function within the for loop? Would like to save them all to one specific folder as well

for i=1:length(unprocessed)
    file_name=unprocessed(i).name;% get name of each file
    [filepath,folder_name,ext]=fileparts(fullfile('R:','Matlab Analysis','1. To be Processed',file_name));%create proper file path with name of each file, create name for folder with data of completed analysis
    [Temp_C, Temp_F, Auger_RPM, Auger_PWM, Fan_PWM]=ExtractDatafromtxt(file_path); %Extract Data From File

savedir = fullfile('R:','Matlab Analysis','1. Processed');
if ~isfolder(savedir); mkdir(savedir); end

for i=1:length(unprocessed)
    file_name = unprocessed(i).name;% get name of each file
    [filepath,folder_name,ext] = fileparts(fullfile(unprocessed(i).folder, file_name));%create proper file path with name of each file, create name for folder with data of completed analysis

    figs_before = findobj(groot, 'type', 'figure');
    
    [Temp_C, Temp_F, Auger_RPM, Auger_PWM, Fan_PWM]=ExtractDatafromtxt(file_path); %Extract Data From File
    
    figs_after = findobj(groot, 'type', 'figure');
   
    figs_created = setdiff(figs_after, figs_before);
    for J = 1 : length(figs_created)
        savefile = fullfile(savedir, "figure_" + folder_name + "_" + J + ".fig");
        savefit(figs_created(J), savefile);
    end
    close(figs_created);
end

Thank you! Works like a charm!

is there any way to save the files as a larger size? Currently looking to save the files as a .pdf, but upon completion the code returns files which are only half the size of the sheet as seen below, would like them to be larger and more readable

within the function code the figures are coded as

PID_Performance=figure('Name','PID Performance','WindowState','maximized','Visible','off');
