to recover that data in case something happens to the encryption key.
If your encryption key is lost or damaged and you don't have a way to
recover your data, the data is lost. You will also lose data if you
store your encryption key on a smart card and the smart card is damaged
or lost. To make sure you can always access your encrypted data, you
should back up your encryption certificate and key. If more than one
person uses your computer, or if you use a smart card to encrypt files,
you should create a file recovery certificate. For more information, see
Create a recovery
certificate for encrypted files.
Based on my further research, you could run cipher.exe tool to display the encryption of foldes and files on NTFS volumes. To do this, please take the following steps.
1) Type "Command Prompt" in the search box and right click to run as Administrator.
2) Type the following command:
cipher /u
Then it will list encrypted folders and files if your system owns.
3) Please locate to the above encrypted folders.
For more information about cipher.exe, please refer to the following website.
