ICBU File – What is .icbu file and how to open it?

ICBU File Format

An ICBU file is a Calendar Backup File created by Apple’s Calendar application. It is an archive file that contains a backup of the calendar events, tasks, and settings from a specific user’s calendar. ICBU files are used to create a backup of a user’s calendar in case of data loss or corruption. They can also be used to transfer calendar data between different computers or devices.

ICBU files are created using the “Export” function in the Calendar application. When a user exports their calendar, they can choose to export it as an ICBU file. The file will be created in the user’s “Documents” folder by default. ICBU files can be imported into the Calendar application using the “Import” function. When a user imports an ICBU file, the calendar events, tasks, and settings from the file will be added to the user’s calendar.

Using Apple Calendar on Mac:

To open an ICBU file on a Mac, ensure you have the latest version of Apple Calendar installed. Locate the ICBU file on your computer, right-click on it, and select “Open With” > “Calendar.” The file will import into your calendar, allowing you to view and edit the events.

Other Methods:

If you don’t have access to Apple Calendar, you can use other methods to open an ICBU file. One option is to convert the file to a more widely supported format, such as ICS or CSV. This can be done using various online file conversion tools or programs like iCal Import and Export. Once converted, you can import the file into your preferred calendar application.

Alternatively, you can use a specialized software program that supports ICBU files. One such program is iCal Buddy, which can open, view, and edit ICBU files. This software is available for both Mac and Windows systems.

Definition and Functionality:

The .ICBU file extension, short for “Calendar Backup File,” is associated with calendar backups created by Apple’s built-in Calendar application on macOS and iOS. These files serve as a means to preserve and restore calendar events, appointments, and other data in the event of device failure or data loss. ICBU files are encrypted for security purposes and can only be accessed and restored using compatible software, such as Apple’s Calendar application.

Advantages and Usage:

ICBU files provide several advantages for calendar management. They allow users to create periodic backups of their calendars, ensuring the safety of their appointments and events. In case of a system crash or data loss, ICBU files can be restored to quickly recover the lost calendar data. Additionally, ICBU files facilitate the transfer of calendar information between different devices, such as from a Mac to an iPhone, making it convenient to keep calendars synchronized across multiple platforms.
