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

what is a .itn file?

ITN files are categorized as data files and known as TomTom Navigator Itinerary Files. These files are the travel itinerary saved using the TomTom Navigator GPS software wherein they are used to save travel routes as well as points of interests in the ASCII text file format. ITN files mark locations as pass-by locations or destination points wherein these points are flagged as either visited or not visited. There are several fields contained in ITN files and these fields are: filed 0 for Longitude in WGS84 format; field 1 for Latitude in WGS84 format; field 2 for Name of the specified point and field 3 for the Flag. ITN files are usually found in “\My Documents\TomTom Navigator Settings" on a Windows operating system and users can create these files or download them online. These files are also available for transfer to a TomTom GPS device using the USB wherein they are saved in the GPS device's ITN folder.

a word of warning

Be careful not to rename the extension on .itn 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, .itn. 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.
