Hello everyone, I had a small doubt how to clear all the contents of the folder 'C:\Project\Template\Simulation\Models' which is saved to a variable. i am using this in my code for which the deletion is not happening.

function filetransfer(Vehicleline,Select_model,Select_KW)

root_src = 'C:\Project';

root_dest = 'C:\Project\Template\Simulation\Models';

root_vehicleline = strcat(root_src,'\',Vehicleline,'\','Models');

root_src_model = strcat(root_vehicleline,'\',Select_model,'\',Select_KW);

locals = dir('C:\Project\Template\Simulation\Models');

if ~isempty(root_dest)

rmdir(root_dest)

copyfile(root_src_model,root_dest);

else

copyfile(root_src_model,root_dest);

end

Thanks in advance!

在 MATLAB Online 中打开

Use

rmdir(root_dest,'s')
%               ^^^ you need this

to also delete all of the folder contents. This is explained in the rmdir documentation, which states that for the syntax you used " folderName must be empty.", but for the syntax that I showed you "rmdir folderName s also attempts to remove all subfolders and files in folderName, regardless of their write permissions."
