C# SDK Сheck if the file is encrypted before opening

[Max921]

1) Is it possible to check if a file is encrypted before opening? If so, how?
2) How to open a file with a given password so that the password entry window does not appear?

Hello again Max921,

Are you using the Viewer SDK?
I moved your other topic from the end user Editor to the Editor SDK section, and answered assuming you were using that one, but if it's another of our SDK products - please do confirm either here or in the other topic.

Kind regards,
Stefan
