MATLAB: Read filenames from folder A and rename files from folder B as filenames if folder A

movefile(source, dest) moves the file from source to dest. The error message means, that the source file is not found.

You did not show or explain it, but it seems like the structs filesA and filesB come from the dir() command. Then note, that the fields name contain the file name only, but not the absolute path with the folder name. Then the file "filesB(i).name" are searched in the currently active folder as replied by cd.

When the filesA are insider C:\Temp\FolderA and for filesB in C\Temp\FolderB, add these names to get absolute files:

pathA = 'C:\Temp\FolderA'
pathB = 'C:\Temp\FolderB'
filesA = dir(fullfile(pathA, '*.ext'));
filesB = dir(fullfile(pathB, '*.ext'));
...
movefile(fullfile(pathB, filenameB), fullfile(pathA, filenameA))

Btw, I did not understand which file should be renamed by which strategy.

MATLAB: Function

plot() is a built-in function so you should not name your own function as plot.
It is better to have an input argument specify the folder so you can use it to apply to many folders.
When load or save, it's always better to specify the full path of the file.
When you try to get the file name, you need to get rid of the .txt extension.
close() needs to specify the figure handle.

function MyPlot(PathStr)
files = dir(fullfile(PathStr,'*.txt'));
for i=1:length(files)
    data = load(fullfile(PathStr,files(i).name));
    filename=strrep(files(i).name,'.txt','');
    f=figure;
    plot(f,data);
    saveas(h,fullfile(PathStr,[filename,'.fig']));
    close(f);
end
