What is an IDI file

IDI files mostly belong to WinRAR. An IDI file is a zipped text archive that uses the ZIP compression method to store internal text data.
Key Technical Details:
  • Format: The file uses ZIP compression, a standard method for reducing file size.
  • Contents: It typically holds text data in a compressed structure.
  • Access Method: These files can be opened with archive tools such as WinRAR (WinRAR official) or WinZip.
  • FilExt.com tip: Although an IDI file may not appear as a standard text file, renaming it to .zip can allow you to extract its contents using common ZIP utilities.

    How do you open IDI files?

    You need a suitable software like WinRAR to open an IDI 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 IDI file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a IDI file directly in the browser:. Just drag the file onto this browser window and drop it.
