CWIKI is a plain text file format featuring wiki markup syntax, originally developed by Atlassian for its Confluence collaboration software. These files are primarily utilized to store project documentation, technical notes, and knowledge base articles in a structured, human-readable format before web rendering. Although now largely considered a legacy format following Confluence’s transition to XHTML-based storage, it remains safe as clear text, though users should maintain standard data privacy protocols when handling exported documentation.
