What is a .cur file?

A .cur file is a Microsoft Windows Cursor. This one is a specialist format without an obvious everyday home.

How to open a .cur file

  • The program that created it is by far the most reliable way to open it.
  • On Windows, use a hex viewer or the free TrID tool to identify what the file really is.
  • On Mac or Linux, running `file yourfile` in the terminal identifies most formats instantly.

The registry records this extension against Microsoft Windows Cursor, so software from that family is the most likely match.

How to convert a .cur file

  • Identify the file first, then look for an export or Save As option in whatever program can read it.

MIME type

When a .cur file travels over the web, servers label it with this MIME type:

image/x-win-bitmap
