In the latest versions of Sookasa (version 3 and above), encrypted files look the same as unencrypted files. So when Sookasa is running and you are logged in, the .sookasa extension will not appear on files inside the Sookasa folder. We hide these extensions when you’re logged in to create a user seamless experience.
But the existence of these extensions is key: They automatically call the Sookasa application to decrypt secure files the moment a you need them, so you never have to think about how to open your files.
If Sookasa is not running, you will see the .sookasa extension on encrypted files within the Sookasa folder and outside our folder. On Dropbox web, you will always see the .sookasa extension in the file name of encrypted files. When Sookasa is either locked or is not running, you will need to authenticate into the app to read the encrypted files.
