Issue using Delete to remove .txt file

Hello everyone. I am currently trying to reomove a .txt file before saving data on it to avoid superposition. I am using Delete as defined in it's help page.

My code is as follows:

delete 'WeightData.txt'
save('WeightData.txt', 'weight', '-ASCII','-append');

However, when I execute it I obtain the following "Warning: File not found or permission denied"

I have also tried to delete using the wildcard

delete '*.txt'

However, the error remains the same and the values keep accumulating in the .txt file.

Can someone please advice me on what to do?

Thanks for reading.

Just use save without '-append'. It should overwrite the old file.
