The “Microsoft User Data” Folder will put in your documents folder when you install Microsoft Office 2011 for Mac
It will always be there no matter how many times you try and delete it. It will be automatically recreated every time you open Microsoft Word or Excel.
This is how and where to relocate it.
Simply move “Microsoft User Data” folder from “Documents” to Users/ (YOUR USER NAME)/Library/Preferences/Microsoft/Office 2011/
If your library folder is not visible take a look at Show User Library Folder in OS X Lion & Mountain Lion
In OS X Lion and Mountain Lion the default setting is to hide the Library folder, probably to stop people from deleting or damaging files that are necessary for OS X Lion to run properly.
The Library folder was visible by default in past versions of Mac OS X, this is how to get it back:-
Show User ~/Library in OS X Lion & Mountain Lion
Open Terminal, and enter the following command to show or hide the directory:
chflags nohidden ~/Library/
The users Library folder will immediately become visible again. Reverting this back to the standard Lion setting is simple too:
Hide User ~/Library in OS X Lion (default setting)
This returns to the default setting of hiding the user Library directory:
chflags hidden ~/Library
Changes take effect immediately again, and Library becomes invisible to the user.
