IRD format details:

If you know the file format, you can also find out how to open or edit the file. 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. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the IRD files is as follows:

The IRD file extension is not widely used. Such a file is used by different programs with different formats. However, the following two file formats are common:

• 45% of all IRD files save the data in GZIP file format. Gzip is a compressed archive file format. Gzip (GNU zip) is only capable of compressing a single file. They consist of illegible, cryptic characters. IRD files are between 6 KB and 290 KB in size. The file type is very recent. An example of a file name is Red Dead Redemption - Game of the Year Edition (USA) (En,Fr,De,Es,It).ird. Files like these have the following tags: blus, bles, bcas and bces.
• 5% of all IRD files start with the magic bytes Channel Intg Period [ms] Avg. [scans] Smoothing [pixels, which are always the first bytes of this file format. 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. IRD files are between 73 KB and 73 KB in size. The following keywords are characteristic: 0.00000E+0, 188.23, 188.51, Avg. [scans], Channel, DATA, Intg Period [ms], Master, Smoothing [pixels] and uW/cm^2/nm. These files are often associated with white and lens.

All the rest of the IRD files (50%) have different formats, often, for example, ZIP. Files like these are sometimes linked to xcruiser, xdsr, skylanders, group, hdpvr or bcus. Just click the "Choose your .ird file to analyze" button on this page to find out what your IRD file is.
