Open the Kaspersky Security Center Administration Console.
In the console tree, select Policies.
Select the necessary policy and double-click to open the policy properties.
In the policy window, select Data Encryption → File Level Encryption.
In the right part of the window, select the Encryption tab.
Remove files and folders that you want to decrypt from the encryption list. To do so, select files and select the Delete rule and decrypt files item in the context menu of the Remove button.
Files and folders removed from the encryption list are automatically added to the decryption list.
As soon as the policy is applied, Kaspersky Endpoint Security decrypts encrypted files that are added to the decryption list.
Kaspersky Endpoint Security decrypts encrypted files if their parameters (file path / file name / file extension) change to match the parameters of objects added to the decryption list.
Kaspersky Endpoint Security postpones the decryption of open files until they are closed.
