mysqldump Error 1045 Access denied despite correct passwords etc

Question

This is a tricky one, I have the following output:

mysqldump: Got error: 1045: Access denied for user \'root\'@\'localhost\' (using password: YES) when tr

Answer 1

The access being denied is probably to the Windows file system not to the MySQL database; try redirecting the output file to a location where your account is allowed to create files.
