For the use of the preview feature of macOS which is also utilized for secure editing, the required file is copied into the Secure Temporary Storage. With this file, the preview or the associated program is started for editing. Thus, the file remains encrypted.
When the file has been edited, it will be immediately re-imported into the safe. If the edited program is closed, the file is deleted from the Secure Temporary Storage.
The Secure Temporary Storage will be unusable after exiting SimpleumSafe. Each time you start SimpleumSafe a new Secure Temporary Storage is created.
