What is an IR file

IR files mostly belong to LIRC. This IR file may be one of several distinct types. Its use depends on its origin and content. Below are some common cases:

Remote control file: This file holds infrared signal instructions used by remote control systems. It is common in setups like LIRC and projects such as IRremoteESP8266. You may open it with a plain text editor to view command codes.

Compressed archive: In some cases, the IR extension appears on multi-part archives. These work much like RAR or ZIP files. Tools such as WinRAR (WinRAR) or 7-Zip are used to extract their contents.

Intermediate Representation: Another use is to act as a container for compiled instructions or printer commands. Examples include parts of a PDF generation process, WordPerfect printer files for HP LaserJet, and installer response files. Here the extension stands for Intermediate Representation and is handled by specialized software.

Impulse response audio file: A smaller group uses IR for storing audio impulse responses used in programs like Audacity (Audacity). These files capture sound profiles to simulate room acoustics.

Script file: Rarely, IR files may contain code or scripting commands for systems like the easyIO framework.

FilExt.com note: When you encounter a IR file, check its internal content (for example, by opening it in a text editor or using a hex viewer) to determine which category it falls into. This can help you decide the correct application to open or work with it.

How to open an IR file

IR file format:

A file format defines how the data in the file is structured. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the IR files:

The IR file extension covers different formats for different programs. However, the following two file formats are common:

• 20% of all IR files start with the bytes 04 F0 49 52, which are crucial for this file format. They consist of unreadable binary data. The files are 310 bytes to 6 KB in size, with a median of 2 KB. The file type is old but is used even today. Several words can almost always be found in the files, e.g. CSP-LIR-USB, 1.018.1897 and Unknown. Files like these have the following tags: daikin, receiver, generic and samsung.
• 10% of all IR files save the data in RAR file format. RAR is a proprietary archive file format that supports data compression, error correction and file spanning. They consist of unreadable binary data. IR files are between 9 MB and 2 GB in size. The keywords Rar! are typical for these files. Files like these have the following tags: downloadly, udemy, complete and design.

The remaining 70% of all IR files are files with no common format, the following 3 formats exist: PDF.
