It looks like all of those drives are mapped drives to a local or network share.
As @Run5k mention you can open a command prompt and type net use
which will list all the network shares accessed including your mapped drives.
However, if it is a local share in File Explorer
, right-click on the "d2" folder and select Properties
. Under the General
tab you should see a Target
field which tells you the address of the share.

Also if you want to check which credentials were used to access the network share, then you can use the Credential Manager
(under Control Panel\User Accounts\Credential Manager), select Windows Credentials
and look through the list for an entry matching the hostname of the share.
