What is an IDR file?

IDR files mostly belong to IDR Viewer. An IDR file is used primarily to store Image Data Resource information. These files are often generated by engineering and CAD applications.

Image Data Resource: The file holds raw image data for design and visualization. It is used by programs such as the IDR Viewer to display engineering images and temporary graphics, sometimes in conjunction with tools like Pro/ENGINEER or Catia.

Invalid Data Report: Some IDR files are created as a log for invalid or error data. This use case, associated with QPAY, records data processing issues rather than storing visual content.

FilExt.com tip: Identify the file's origin before opening it. Use the appropriate software to view or process the content, and avoid using simple text editors for files that use proprietary binary formats.

How to open an IDR file

You need a suitable software like IDR Viewer to open an IDR 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.

IDR file format:

To find out what program is needed to open IDR files, you need to determine the file format. The file format can be determined based on the file extension and the signature (the first few characters of a file). 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.

Certain words are almost always found in the files, such as DW98DW98DW98 and ISOF. Such files are related to inst.
15% of all IDR files use the same file format, which can be identified by the letters "REPORT INVALID DATA " at the beginning. The content consists of readable text data, which can be read using a text editor. The file size is in the range of 1 KB to 2 KB. The keywords REPORT INVALID DATA STANDARD FILE INTERCHANGE PAGE : 1 and RUN ON are typical for these files. These files are attributed to llins, salaries, payment and qpay.
