.icaltodo File Extension

Developer: Apple
File type: iCal To Do File
You're here because you have a file that has a file extension ending in .icaltodo. Files with the file extension .icaltodo can only be launched by certain applications. It's possible that .icaltodo files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .icaltodo file?

Like the ICALEVENT file extension, the ICALTODO file extension is also used by Spotlight. ICALTODO refers to the iCal To Do Files or calendar data files that are mostly used by the Spotlight utility; a tool that belongs to the MAC OS X and is used as a search utility. While the ICALEVENT files contain calendar event data, the ICALTODO files usually contain tasks and to-do lists of users as well as cached to-do data also useful for searches. These files are saved in the [user]/Library/Caches/Metadata/iCal/ directory. In other words, they correspond to the calendar to-do items users created using Ical. ICALTODO files are mostly used and opened using the Apple Ical application by MAC. This is known as a personal calendar wherein users can create their schedules, tasks, reminders, etc. It helps users take note of the important events and important things to do on a certain date or schedule.

how to open a .icaltodo file?

Launch a .icaltodo file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .icaltodo file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .icaltodo files aren't yet associated with it. In this case, when you try to open a .icaltodo file, you can tell Windows which application is the correct one for that file. From then on, opening a  .icaltodo file will open the correct application. Click here to fix .icaltodo file association errors

Apple iCal

Apple iCal

Apple iCal is a personal calendar software that has tools that enable a user to manage his appointments, schedules and other reminders that are personally essential. The name iCal was licensed from Brown Bear Software since 1997. However, before the OS X Mountain Lion was released, iCal was rebranded as simply Calendar last July 2012, which was the first calendar tool for OS X that had support for different calendars with management tools. This was designed by a French team with Jean-Marie Hullot as the leader who’s also known as a friend of Steve Jobs. It is a program compatible for Mac OS X 10.5, Mac OS X 10.6, Mac OS 10.7, OS X Lion and OS X 10.8. What a user can do with iCal are the following: open iCal from the Applications folder or the Dock, create New Calendar from the File menu, schedule an event or create a reminder on the calendar, publish or share calendar using iPad, iPod or iPhone with the option to synchronize, set up iCloud calendar, CalDAV or Exchange calendar account, and subscribe to calendars of other users.

a word of warning

Be careful not to rename the extension on .icaltodo files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .icaltodo. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
