Why do I get an error 36 (Command contains unrecognized phrase/keyword) when trying to load a file into MMS WIN or when MMS WIN is trying to output a file?

Ensure that there are no ‘spaces’ found in the path where the file is located or being written to, i.e. a file located under “My Documents” would cause this error. Copy the file to another directory and then run the process where the problem occurred.
