What is a .ICALTODO file?
The file extension .ICALTODO is associated with a type of file called an iCal To Do File. This kind of file is related to calendar information and is specifically used by a feature on Mac computers called Spotlight. Spotlight is a tool that helps you search for files and information on your computer quickly. The .ICALTODO file contains information about tasks or "to-dos" that you have added to your calendar, and this information is used by Spotlight to help find things faster.
These files are usually stored in a special folder on your Mac. The path to this folder is [user]/Library/Caches/Metadata/iCal/. This means that the file is saved in a cache directory under the user's Library folder, specifically in a subfolder for iCal metadata. It's important to note that these files are not meant to be opened directly by users, as they are used internally by the system to improve search functionality.
However, if you do want to view or manage your calendar to-dos, you can use a program called Apple Calendar. Apple Calendar comes included with the operating system on Mac computers, so you don't need to download or install anything extra to use it. This program allows you to create, view, and manage your calendar events and to-do items directly.
It's worth mentioning that Apple Calendar was previously known as Apple iCal. The name change happened in 2012 when Apple released a new version of its operating system, OS X Mountain Lion. So, if you're using a Mac that's been updated since 2012, you'll be looking for Apple Calendar, not Apple iCal, to manage your .ICALTODO files and other calendar-related tasks.
