As previously mentioned in another thread: http://support.solidexplorer.pl/responses/lock-deletion-for-wholle-folders-and-maybe-files-too

It would be great if in the future users could collate a list of folders/files that have to require exclusive permission before being deleted...This would only be to prevent accidental deletion from within Solid Explorer.

This feature would be for Solid Explorer internally only.

I am not talking about Encryption I am talking about a padlock in the form of a long passcode or removing the lock from within the settings.
