.CTD File Extension

Users typically save Cherrytree documents as .CTB or .CTX files. They may also save documents in XML to save storage space. The documents saved in XML format are saved as CTD files and password-protected CTD files are saved as CTZ files.

CTD files are typically opened by Cherrytree. However, they may also be opened by XML and text editors.

NOTE: Cherrytree is developed by giuspen, a portmanteau of Giuseppe Penone.
