Details:

it appears that failed file operations fail silently in the GUI.  Example:


>> a = fopen('testfile.txt','w');

## testfile.txt file created and visible in File Browser

>> delete('testfile.txt')
warning: delete: testfile.txt: Permission denied
warning: called from
    delete at line 58 column 11

>> rename testfile.txt test2.txt
ans = -1


GUI right click testfile.txt, select Delete.  Get 'Are you sure' prompt.
select Rename, get the 'Rename file/directory' prompt. Selecting Yes or OK,
respectively, produces no result or warning. I would expect an alert of some
kind that the operation has failed. 

as expected after a 

fclose (a) 


the functions perform as expected.
