Using load function unexpectedly deleting original .mat file

When I load variables into the workspace from a .mat file, MATLAB then deletes the original file.

Does anybody know why this is happening?

Thank you.

Hello, I was trying to post the full output but my comment was getting flagged for potential spam. Here is the first part of the output...

built-in (C:\Program Files\MATLAB\R2016b\toolbox\matlab\general\load)

I have circumvented the issue at the moment by saving the workspace variables back to a file of the same name after I have finished with them, however would like to know why this is occuring. It's never happened before.

My code that I'm using with it is:

   for i = 1:length(list)

      filename = char(list(i)) ;
      disp(filename); 
      %ensure not to go out of bounds
      if i ~= length(opFlowVariables)
          load(filename) ; 
          main(vx, vy, i, outputFolder) ;
      end
    end

Here, I am just going through all the files, loading the variables 'vx' and 'vy' and using them in 'main'.

Is that the bad code, or the circumvented/working code? I don't see any line of code that would delete a .mat file, unless main() does it internally.

Hello,

I found the bug. When I was saving a variable to a file elsewhere in the code, I was using the same filename which caused some issues. Nevertheless thank you for your help.
