Opening INO Files

The INO file type is primarily associated with Arduino.

What is an INO file

INO files mostly belong to Arduino by Arduino. An INO file is a program (sketch) created with Arduino IDE. An Arduino sketch is written in C++ programming language. The file is compiled to binary format before it is deployed to an Arduino microcontroller board. Another type of INO file contains a script used to automate processes within Inno Setup software installer for Windows operating system. INO is also the filename extension of some data file used by IPRO temperature transmitter configuration software.

How can I open an INO file?

You need a suitable software like Arduino to open an INO file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your INO file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a INO file directly in the browser:. Just drag the file onto this browser window and drop it.

How to extract texts from INO files or capture a screenshot to PDF, JPG, DOCX, TXT, ...

If you want to extract texts from INO file or capture a screenshot, you can use our free Online INO File Viewer:

To do this, click the button "Choose your .ino file to view" on this page.
After your file is opened in browser,
click "Save as..." in the menu.
Then choose the file format (e.g. JPG, PDF, DOCX, TXT, ...) you want.
Download the converted file.

Programs that open and convert INO files:

Arduino by Arduino
See the previous paragraphs to learn more about the main application. INO files are often referred to as Arduino developers because this type of file is primarily created or used by this software.
Inno Setup (script) by Jordan Russell
Inno Setup is a third-party program used to install programs on Windows operating system. INO is the filename extension of a script used to automate its internal operations. This file format is classified as Developer.
IPRO (data) by INOR
IPRO is a Windows program for configuring and programming temperature transmitters such as the IPAQ-HX and IPAQ-LX modules manufactured by INOR. It uses some data saved in an INO file. This file format is classified as Developer.

INO file extension format:

If you know the file format, you can also find out how to open or edit the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. If there are problems opening a file, you must first determine the file format used. Our evaluation of the INO files looks like this:

The INO file extension is quite widespread and includes different formats for the applicable programs. The file formats most commonly found in INO files are:

65% of all INO files are using the well-known Source file format to store the data. A source code is the set of instructions written by a programmer using a computer programming language like JavaScript, C++ or Basic. This code is translated into machine language by a compiler. The translated result is called app, program or executable. The content consists of readable text data, which can be read using a text editor. The average file size is 2 KB with most files being between 690 bytes and 7 KB in size. The file type was developed only in the last few years. The files contain the following words: include and define. Files like these are sometimes connected to code, arduino, sketch, project, robot, system, program and door.
1% of all INO files start with the bytes byte crucial for this file format. The contents of these files are easily readable with a text editor. The file size is in the range of 1 KB to 3 KB. Certain words are almost always found in the files, such as byte, bool and void setup() {.

All other INO files (34%) have no uniform format, frequently e.g. String and char. Sometimes used for level, motor, smart, bluetooth, line, ultrasonic, obstacle or blink. Just click the "Choose your .ino file to view" button on this page to find out what your INO file is.

an ino sketch is a special file format by Arduino and should only be edited and saved with the appropriate software.

How to solve problems with INO files

Associate the INO file extension with the correct application.
Update your software that should actually open sketches. Because only the current version supports the latest INO file format. Search, therefore, e.g. on the Arduino manufacturer website after an available Arduino update.
To make sure that your INO file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
