When a exclusion is created for a file or folder, the following registry items are created by Symantec Endpoint Protection (SEP):
HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\AV\Exclusions\ScanningEngines\FileName\Admin
The file exclusion defined by Symantec Endpoint Protection Manager (SEPM) will be stored under this key.
HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\AV\Exclusions\ScanningEngines\FileName\Client
The customized file exclusion will be stored under this key.
HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\AV\Exclusions\ScanningEngines\Directory\Admin
The directory exclusion defined on SEPM will stored under this Key
HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\AV\Exclusions\ScanningEngines\Directory\Client
The customized directory exclusion will be stored under this Key
SEP will create a ten digit key for every exclusion file or directory and it will be a unique value.
If the file or folder is same path on different clients, they will have the same digital key under the key Admin or Client.
