• Integrated calendar with multiple views. The calendar module displays events and appointments in daily, weekly, monthly, and annual formats. Each entry supports titles, locations, detailed descriptions, and customizable recurrence patterns. Visual scheduling tools highlight time overlaps and availability, facilitating short-term and long-term planning across all calendar views.
• Advanced contact management. The address book incorporates extensible fields for storing names, multiple phone numbers, email addresses, websites, postal addresses, photographs, and user-defined data points. Contacts are organized into categories and groups, with search and filtering functions enabling rapid information retrieval from large directories.
• Task management with priorities and progress tracking. The task manager supports creation of activity lists with assigned priority levels, due dates, completion percentages, and status tracking. Each task can be divided into subtasks, linked to reminders, and used to generate productivity reports based on defined deadlines and completion metrics.
• Hierarchical notebook structure. The notes module allows document creation in a tree-based hierarchy, organizing folders and subfolders for categorizing memos, ideas, personal records, or technical documentation. Notes include rich text formatting, table insertion, images, and attached files for comprehensive documentation.
• Configurable reminders with multimedia alerts. Each event, task, or appointment can be linked to reminders programmed with customizable advance notice periods. Alerts appear as on-screen notifications and can be supplemented with playback of user-selected audio files, ensuring timely notification of commitments.
• Reusable data templates. The platform includes a template system that allows predefined structures for contacts, events, and recurring tasks. Users establish default fields, date formats, and category assignments, reducing data entry time for repetitive information patterns.
• Export and import across multiple formats. Data managed within C-Organizer transfers through CSV, TXT, XML, vCard (VCF), and iCalendar (ICS) file formats. This functionality enables migration from other calendar or address book applications, as well as integration with mobile devices and external services through standardized data exchange.
• Custom report and agenda printing. The system generates printed documents with configurable layouts, including monthly calendars, contact listings, pending task reports, and notebook compilations. Printing options allow selection of date ranges, specific categories, and formatting styles to match documentation requirements.
• Password and secure data management. The professional edition incorporates an encrypted storage module for passwords, banking credentials, software licenses, and other sensitive information. Records are protected by a master password and utilize encryption algorithms to maintain confidentiality of stored data.
• Global search with advanced filtering. The interface includes a search engine that simultaneously examines calendars, contacts, tasks, and notes. Filters narrow results by dates, categories, keywords, or completion statuses, presenting findings in a consolidated view for efficient information discovery.
• Custom categories and user-defined fields. Users define their own categories for classifying events, contacts, and tasks according to specific requirements. Additionally, custom data fields can be added to any record, adapting the information structure to different professional domains or personal organizational methods.
• Mobile device synchronization through files. Through vCard and iCalendar formats, data transfers to smartphones and tablets without requiring cloud service connections. This method maintains information consistency across devices while operating independently of external platforms.
• Productivity statistics. The program generates metrics on completed tasks, executed events, and daily activity patterns. Statistical reports present data through charts and summary tables, providing visibility into time allocation and objective fulfillment across defined periods.

C-Organizer was developed by CSoftLab, a company established in 1998 specializing in productivity and personal organization software. Initial development of the application began in 2003 with the objective of delivering an integrated solution combining calendar, address book, and task management within a unified environment. The first public version was released in 2004, and since then the product has maintained regular updates that expanded its feature set. The software core is written in the C++ programming language using Borland C++ Builder in its initial versions, subsequently migrated to Embarcadero C++ Builder to ensure compatibility with recent Windows releases. The application architecture employs native Windows API libraries to optimize performance in local data management. CSoftLab continues to develop the C-Organizer product line across Lite, Professional, and Network editions, maintaining compatibility from Windows 7 through Windows 11.
