ITN file format:

To view or edit ITN files you need to know the file format, because it determines how the data in this file is stored. The file format can be determined based on the file extension and the signature (the first few characters of a file). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below is our analysis of the ITN files:

As a file extension, ITN isn't very common and covers a large number of different file formats. The two most popular formats are as follows:

• 5% of all ITN files start with the magic bytes 13, which are always the first bytes of this file format. The content consists of readable text data, which can be read using a text editor. The files are on average 450 bytes in size and range from 120 bytes to 1 KB.
• 5% of all ITN files save the data in UTF-8 file format. UTF-8 is the World Wide Web's most common character encoding for Unicode. UTF-8 files can be viewed with any text editor. These files start with the 3 bytes  (hex: EF BB BF), the so called byte order mark (BOM). These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. The average file size is 370 bytes with most files being between 130 bytes and 1 KB in size.

The remaining 90% of all ITN files are different files with different signatures, frequently e.g. QANTIM Itinerary. Files like these are sometimes linked to tour, route, aller, gardasee, portugal, ajaccio, anfahrt, driving, vogesen, calais, alpes, runde, fore or home.
