After installing Office 2011 for Mac OS, a folder called ‘Microsoft User Data’ will be created in your favourite ‘Documents’ folder.
I have no idea why Microsoft is creating such application related files in my Documents folder. There are other places where they can keep such configuration files.
However, if you want to get rid of this folder, you should move it in the ‘Preferences’ folder located in ‘
/Users/<username>/Library/Preferences‘. Not that there exists also another folder with the same name found in ‘
/Library/Preferences‘, but this is not the right location you need.
To move the folder you can run following command in terminal:
mv /Users/<username>/Documents/Microsoft\ User\ Data/ /Users//Library/Preferences/
