Hi Zacharias,
You might be able to find the drive mappings in the registry:
I found this: http://sysadminslibrary.blogspot.com.au/2013/02/mapped-network-drives-in-windows-7.html
It partially reads
"...created under the following key in registry: HKEY_CURRENT_USER\Network
.. a network drive with letter “W” the key will be “HKEY_CURRENT_USER\Network\W"
the UNC is the RemotePath key
HTH
