Unique Identifiers In Windows Explorer

My Windows 8 runs on VirtualBox which in turn is hosted on Ubuntu. In Ubuntu I have a folder called Documents, specifically it is at homeuserNameDocuments. In Windows I have a folder called Documents, specifically it is at C:UsersuserNameDocuments. I can see this from Windows Explorer when I right click "My Documents" and then the tab "Location". In the "Location" tab there is the path C:UsersuserNameDocuments.

This is risky since Windows Explorer identifies the folder as "My Documents" when in actual fact it is "Documents" as visible in the "Location" tab.

I need to eliminate user errors caused by belief that the folder name is "My Documents".

At this point an example of such an error may be appropriate, but I think it's so obvious that an example is a painfully boring distraction. One user error might be that if the user copies "My Documents" to E: (which points to homeuserName in Ubuntu) he would expect that "homeuserNameMy Documents" will be created parallel to "homeuserNameDocuments". In fact, what will happen is that the folder from Windows is actually named "Documents", contrary to the appearance in Windows Explorer, and the contents there will become intermingled with the documents that were already present in homeuserNameDocuments. This is a disaster. In general identifying things non-uniquely creates risk. In general we need one-to-one identfiers to minimize error recovery effort.

I need a permanent solution that is not manual. That is, I do not want to manually remove the prefix "My ". I did this before but somehow, perhaps in the upgrade from Windows 7 to Windows 8, the prefix reappeared.
