What is a CTZ file

CTZ files mostly belong to Cherrytree by giuspen. CTZ files are used by Custody Toolbox, a program for organisation of a custody situation.

Main Usage: CTZ files store backup data for Custody Toolbox, which contains several tools for aiding a user in the organisation of a child custody situation. The file allows for a user to recover their data in case that data is lost or unintentionally modified. The backup file can be stored on the same device if the purpose is to create an image from which a user's data can be restored. A user could also store the CTZ file on a separate storage device to guard against data loss in the event that their primary storage device were to fail.
Support: Custody Toolbox is compatible with the Windows operating system. There are no known third-party applications that support CTZ files for other popular operating systems, such as MacOS and Linux.
Other Uses: The CTZ file extension may also refer to a Cherrytree Password Protected Data file, a password-protected file for the note-taking application, Cherrytree.
